Errors loading Commands and Listeners on bun run

When trying to run application via bun run, receive errors for each command and listener created. Here the following error: 
 Error when loading '/home/thrump/projects/botc/src/commands/createChannel.ts':  9 |   LoaderErrorType2["UnknownStore"] = "UNKNOWN_STORE";
10 |   return LoaderErrorType2;
11 | })(LoaderErrorType || {});
12 | var _LoaderError = class _LoaderError extends Error {
13 |   constructor(type, message) {
14 |     super(message);
         ^

Here is an example of a file (very barebone): 
import { isMessageInstance } from "@sapphire/discord.js-utilities";
import { Command } from "@sapphire/framework";

export class CreateChannelsCommand extends Command {
  public constructor(context: Command.LoaderContext, options: Command.Options) {
    super(context, { ...options });
  }

  public override registerApplicationCommands(registry: Command.Registry) {
    registry.registerChatInputCommand((builder) =>
      builder
        .setName("createChannels")
        .setDescription("Will create individual channels for each player")
    );
  }

  public async chatInputRun(interaction: Command.ChatInputCommandInteraction) {
    console.log("test");
  }
}
import { isMessageInstance } from "@sapphire/discord.js-utilities";
import { Command } from "@sapphire/framework";

export class CreateChannelsCommand extends Command {
  public constructor(context: Command.LoaderContext, options: Command.Options) {
    super(context, { ...options });
  }

  public override registerApplicationCommands(registry: Command.Registry) {
    registry.registerChatInputCommand((builder) =>
      builder
        .setName("createChannels")
        .setDescription("Will create individual channels for each player")
    );
  }

  public async chatInputRun(interaction: Command.ChatInputCommandInteraction) {
    console.log("test");
  }
}
Solution:
i see the issue now: the documentation mentions to set your "main" in the package.json to the src/index.js, so in my head i assumed it needed to point to my src/index.ts. but i guess based off the outDir in the tsConfig, have to point to dist/index.js...

What's your tsconfig? Also are you sure you're using bun and not Deno because the error has node_modules/.deno

@Boomeravna , sorry i was also testing to see if it was a bun runetime compiler/runetime issue so tried it with Deno but they both gave the same error decided to also give other configurations of the tsconfig.json, so tried this as well: 
"compilerOptions": {
    "lib": ["es2023"],
    "module": "node16",
    "target": "es2022",

    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "moduleResolution": "node16"
  }
"compilerOptions": {
    "lib": ["es2023"],
    "module": "node16",
    "target": "es2022",

    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "moduleResolution": "node16"
  }
same error

That seems fine at a glance. Make sure to nuke your node_modules between Deno and Bun tries. And for bun you can compare with https://github.com/sapphiredev/node-bun-example which is a known working sample.

Sure, I'll try taking a look at this and nuke my node modules. One thing I did notice before my power went out, the file that's loading in the files, there was a check to see if it the file was a ts file and if it's an ESMmodule export and that ESMmodule was false So something related to esm module In the @sapphire/pieces

Setting "type": "module" in the package.json ensures sapphire loads in ESM mode

hmm, so i did update my package.json to type:"module" now and i can see that this.clientUsesESModules now returns true, so it grabs the url and appends the searchParams. so it looks like this: 
URL {
  href: "file:///home/thrump/projects/botc/src/commands/unmute.ts?d=1721576525813&name=unmute&extension=.ts",
  origin: "null",
  protocol: "file:",
  username: "",
  password: "",
  host: "",
  hostname: "",
  port: "",
  pathname: "/home/thrump/projects/botc/src/commands/unmute.ts",
  hash: "",
  search: "?d=1721576525813&name=unmute&extension=.ts",
  searchParams: URLSearchParams {
    "d": "1721576525813",
    "name": "unmute",
    "extension": ".ts",
  },
  toJSON: [Function: toJSON],
  toString: [Function: toString],
}
URL {
  href: "file:///home/thrump/projects/botc/src/commands/unmute.ts?d=1721576525813&name=unmute&extension=.ts",
  origin: "null",
  protocol: "file:",
  username: "",
  password: "",
  host: "",
  hostname: "",
  port: "",
  pathname: "/home/thrump/projects/botc/src/commands/unmute.ts",
  hash: "",
  search: "?d=1721576525813&name=unmute&extension=.ts",
  searchParams: URLSearchParams {
    "d": "1721576525813",
    "name": "unmute",
    "extension": ".ts",
  },
  toJSON: [Function: toJSON],
  toString: [Function: toString],
}
but i guess the return mjsImport(url) returns back an empty object i guess ill try to look more in the example one, but the example one seems a bit weird, cause you essentially serve the bun.ts who then imports the main.ts to run is there a particular reason for that approach

so now errors dont throw. though it seems my slash commands or listeners aren't still registered. for the example above, i put in the event for voiceStateUpdate, and tested just joining a VC to see a console.log be fired, but didn't seem like anything got fired
