Getting "Unknown message" sometimes...

yo. Excluding command handling I have something like this:

client.on("interactionCreate", (interaction: Interaction) => {
    // if interaction is component I run execution method
    const loadingContent = loadingEmoji ? `<a:${loadingEmoji.name}:${loadingEmoji.id}>` : "...";
    const message = await interaction.reply({ content: loadingContent, ephemeral: true, fetchReply: true }) : null;
    reply(opts: ...) {
        delete opts .ephemeral;
        await message.edit(opts as ...);
    }
    // here are some actions. they are takes 2-30secs
    // and at the end I run reply function to send a message
    const error = await reply({ content: null, embeds: [...], files: [...] }).then(() => null).catch((e: Error) => e);
    // sometimes error is null, sometimes its not
});

client.on("interactionCreate", (interaction: Interaction) => {
    // if interaction is component I run execution method
    const loadingContent = loadingEmoji ? `<a:${loadingEmoji.name}:${loadingEmoji.id}>` : "...";
    const message = await interaction.reply({ content: loadingContent, ephemeral: true, fetchReply: true }) : null;
    reply(opts: ...) {
        delete opts .ephemeral;
        await message.edit(opts as ...);
    }
    // here are some actions. they are takes 2-30secs
    // and at the end I run reply function to send a message
    const error = await reply({ content: null, embeds: [...], files: [...] }).then(() => null).catch((e: Error) => e);
    // sometimes error is null, sometimes its not
});

How is it possible that the Message's author is equivalent to null?

TypeError: Cannot read properties of null (reading 'id')

Access error using a channel deletion method

Yo. When I add my bot to the guild I request ManageChannels & ManageRoles permissions. Right now on my test server I found a rather strange error.

voiceChannel.delete()
    .then(() => {
        // posting result to logs
    })
    .catch((e) => {
        console.error(e); 
        // posting error to logs
    });

voiceChannel.delete()
    .then(() => {
        // posting result to logs
    })
    .catch((e) => {
        console.error(e); 
        // posting error to logs
    });

If I right now execute this function with current perms. The channel will be successfully deleted. --- I wanted to add a command to block this channel. I execute it like this:

voiceChannel.permissionOverwrites.cache.forEach(async (perm) => {
  if (perm.type == OverwriteType.Role) {
        if (perm.id != interaction.guild.members.me.roles?.botRole?.id) {
            channel.permissionOverwrites.edit(perm.id, { 'Connect': dbChannel.locked }).catch(() => {});
          } else {
            // do nothing for now
          }
    }
});

voiceChannel.permissionOverwrites.cache.forEach(async (perm) => {
  if (perm.type == OverwriteType.Role) {
        if (perm.id != interaction.guild.members.me.roles?.botRole?.id) {
            channel.permissionOverwrites.edit(perm.id, { 'Connect': dbChannel.locked }).catch(() => {});
          } else {
            // do nothing for now
          }
    }
});

But after executing this command, the bot loses the ability to delete this channel.

DiscordAPIError[50001]: Missing Access
...
{
  rawError: { message: 'Missing Access', code: 50001 },
  code: 50001,
  status: 403,
  method: 'DELETE',
  url: 'https://discord.com/api/v10/channels/1013544243534504067',
  requestBody: { files: undefined, json: undefined }
}

DiscordAPIError[50001]: Missing Access
...
{
  rawError: { message: 'Missing Access', code: 50001 },
  code: 50001,
  status: 403,

  url: 'https://discord.com/api/v10/channels/1013544243534504067',
  requestBody: { files: undefined, json: undefined }
}

I checked the permissions of the bot before blocking the channel - and after. Didn't notice the difference.

How can I check if I can overwrite channel permissions?

I prefer to check permissions before acting. So if I want to create a channel I check

if (categoryChannel.permissionsFor(guild.members.me).has([ PermissionsBitField.Flags.ViewChannel, PermissionsBitField.Flags.ManageChannels ], true)) {
// ok 
}

if (categoryChannel.permissionsFor(guild.members.me).has([ PermissionsBitField.Flags.ViewChannel, PermissionsBitField.Flags.ManageChannels ], true)) {
// ok 
}

So, how can I check if I can overwrite channel permissions? In what situations might a bot not have enough perms to perform this action? What kind of bitField is needed to execute lockPermissions()?
