❔ error: Unable to create a 'DbContext' of type '' ". When adding migration to MySQL database

hi there! im just starting a webapi project and i wanted to use a mysql docker container and go code-first using the entity framework, however, im having troubles trying to add migrations, im getting the following error

Unable to create a 'DbContext' of type ''. The exception 'Method not found: 'Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping.Clone(Microsoft.EntityFrameworkCore.Storage.RelationalTypeMappingInfo ByRef)'.' was thrown while attempting to create an instance. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

in theory, i have my dbcontext declared

namespace Mama.Data {
    public class AppDbContext : DbContext {
        public AppDbContext(DbContextOptions<AppDbContext> options) : base(options) { }

        public DbSet<User> Users { get; set; }
        public DbSet<Category> Categories { get; set; }
        public DbSet<Order> Orders { get; set; }
        public DbSet<OrderStatus> OrderStatuses { get; set; }
        public DbSet<OrderedProduct> OrderedProducts { get; set; }
        public DbSet<Product> Products { get; set; }
        public DbSet<Service> Services { get; set; }
        public DbSet<UserRole> UserRoles { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder) { 
            base.OnModelCreating(modelBuilder);
        }
    }
}

namespace Mama.Data {
    public class AppDbContext : DbContext {
        public AppDbContext(DbContextOptions<AppDbContext> options) : base(options) { }

        public DbSet<User> Users { get; set; }
        public DbSet<Category> Categories { get; set; }
        public DbSet<Order> Orders { get; set; }
        public DbSet<OrderStatus> OrderStatuses { get; set; }
        public DbSet<OrderedProduct> OrderedProducts { get; set; }
        public DbSet<Product> Products { get; set; }
        public DbSet<Service> Services { get; set; }
        public DbSet<UserRole> UserRoles { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder) { 
            base.OnModelCreating(modelBuilder);
        }
    }
}

and my program builds with it

var builder = WebApplication.CreateBuilder(args);
{
    var dbConn = builder.Configuration["Database:Connection"];
    var dbVersion = new MySqlServerVersion(new Version(8, 1));

    builder.Services.AddDbContext<AppDbContext>(ctx => ctx
        .UseMySql(dbConn, dbVersion)
        // TODO: Remove on prod
        .LogTo(Console.WriteLine, LogLevel.Information)
        .EnableSensitiveDataLogging()
        .EnableDetailedErrors()
    );
    ...
}

var builder = WebApplication.CreateBuilder(args);
{
    var dbConn = builder.Configuration["Database:Connection"];
    var dbVersion = new MySqlServerVersion(new Version(8, 1));

    builder.Services.AddDbContext<AppDbContext>(ctx => ctx
        .UseMySql(dbConn, dbVersion)
        // TODO: Remove on prod
        .LogTo(Console.WriteLine, LogLevel.Information)
        .EnableSensitiveDataLogging()
        .EnableDetailedErrors()
    );
    ...
}

could someone give me a hand? what am i missing?

how to set and track audio player states?

hi there, im learning data structures and algorithms and i thought it would be a nice exercise using them in a discord bot that takes a local folder and creates a track instance and plays it according to an initialized DSA... the thing is, i need to keep track of the player status, but it seems that if (player.state === AudioPlayerStatus.__) have no overlap and it complains, ive seen some player.on(___, async () =>) implementations but looks confusing and verbose, is there any way to properly track and set player states to ensure the behaviour of a queue, stack or whatever?

    try {
      TrackQueue.enqueue(track);
      const currTrack = TrackQueue.peek();

      if (typeof currTrack !== "undefined") {
      // player.state === 'idle', but it triggers anyway and returns this interaction
        if (AudioPlayerStatus.Playing) { // Adds
          return await interaction.followUp({
            ephemeral: true,
            content: `Added to the queue... ***${currTrack.title}***`,
          });
        }

        player.play(currTrack.res);

        await interaction.followUp({
          ephemeral: true,
          content: `Now playing... [${currTrack.title}](${currTrack.path})`,
        });

        return entersState(player, AudioPlayerStatus.Playing, 5000);
      }
    } catch (error) {
      console.log(error);
      return await interaction.followUp({
        ephemeral: true,
        content:
          "Something went wrong playing and maybe I crashed, but I'll be back... I hope so :anguished:",
      });
    }

    try {
      TrackQueue.enqueue(track);
      const currTrack = TrackQueue.peek();

      if (typeof currTrack !== "undefined") {
      // player.state === 'idle', but it triggers anyway and returns this interaction
        if (AudioPlayerStatus.Playing) { // Adds
          return await interaction.followUp({
            ephemeral: true,
            content: `Added to the queue... ***${currTrack.title}***`,
          });
        }

        player.play(currTrack.res);

        await interaction.followUp({
          ephemeral: true,
          content: `Now playing... [${currTrack.title}](${currTrack.path})`,
        });

        return entersState(player, AudioPlayerStatus.Playing, 5000);
      }
    } catch (error) {
      console.log(error);
      return await interaction.followUp({
        ephemeral: true,
        content:
          "Something went wrong playing and maybe I crashed, but I'll be back... I hope so :anguished:",
      });

bot joins to voice channel, doesn't play any sound, times out and disconnects

hi there! im following the basic example repo, although is a common error, i wonder, since i basically have the same code as the repo

const player = createAudioPlayer();

const playSong = () => {
  const resource = createAudioResource(
    "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3",
    { inputType: StreamType.Arbitrary }
  );
  player.play(resource);

  return entersState(player, AudioPlayerStatus.Playing, 5000);
};

// TODO: Refactor in its own file
const connectToChannel = async (channel: VoiceBasedChannel) => {
  const connection = joinVoiceChannel({
    channelId: channel.id,
    guildId: channel.guild.id,
    adapterCreator: createDiscordJSAdapter(channel),
    selfDeaf: false,
    selfMute: false,
  });

  // FIX: It connects but the status is not correctly set so it never plays
  // FIX: Times out instead of entering idle
  try {
    await entersState(connection, VoiceConnectionStatus.Ready, 30_000);

    return connection;
  } catch (err) {
    connection.destroy();

    throw err;
  }
};

const player = createAudioPlayer();

const playSong = () => {
  const resource = createAudioResource(
    "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3",
    { inputType: StreamType.Arbitrary }
  );
  player.play(resource);

  return entersState(player, AudioPlayerStatus.Playing, 5000);
};

// TODO: Refactor in its own file
const connectToChannel = async (channel: VoiceBasedChannel) => {
  const connection = joinVoiceChannel({
    channelId: channel.id,
    guildId: channel.guild.id,
    adapterCreator: createDiscordJSAdapter(channel),
    selfDeaf: false,
    selfMute: false,
  });

  // FIX: It connects but the status is not correctly set so it never plays

  try {
    await entersState(connection, VoiceConnectionStatus.Ready, 30_000);

    return connection;

another bot not joining the voice channel

Hi there, im learning my way through the docs and making my first bot, i was following line by line the basic example repo from discord/voice (https://github.com/discordjs/voice-examples/blob/main/basic/src/main.ts) but its not working, its basically the same code minus the formatting and the difference in current Status comparison since it seems the deesctructuring of Constants for Events, Status is not longer used... the code logs is ready to play but when i type -join on the chat it doesnt respond at all, is it because of the intents?

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildVoiceStates,
    GatewayIntentBits.GuildMessages,
  ],
});

//ready(client);

client.on("ready", async () => {
  console.log("Discord.js client is ready!");

  try {
    await playSong();
    console.log("Song is ready to play!");

  } catch (error) {
    console.error(error);
  }
});

client.on("messageCreate", async (message) => {
  if (!message.guild) return;

  if (message.content === "-join") {
    const channel = message.member?.voice.channel;

    if (channel) {
      try {
        const connection = await connectToChannel(channel);

        connection.subscribe(player);
        await message.reply("Playing now!");
      } catch (error) {
        console.error(error);
      }
    } else {
      void message.reply("Join a voice channel then try again!");
    }
  }
});

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildVoiceStates,
    GatewayIntentBits.GuildMessages,
  ],
});

//ready(client);

client.on("ready", async () => {
  console.log("Discord.js client is ready!");

  try {
    await playSong();
    console.log("Song is ready to play!");

  } catch (error) {
    console.error(error);
  }
});

client.on("messageCreate", async (message) => {
  if (!message.guild) return;

  if (message.content === "-join") {
    const channel = message.member?.voice.channel;

    if (channel) {
      try {
        const connection = await connectToChannel(channel);

        connection.subscribe(player);
        await message.reply("Playing now!");
      } catch (error) {
        console.error(error);
      }
    } else {
      void message.reply("Join a voice channel then try again!");
    }
  }
});
