Resolving 'dynamically imported module evaluation pending, but no pending ops'

I've been getting this error quite a lot, but I haven't found a single way to know which unresolved promises cause it.

 error: Dynamically imported module evaluation is still pending but there are no pending ops. This situation is often caused by unresolved promises.
Pending dynamic modules:
- file:///home/user/Desktop/js/denolasvegas/commands/main/CATEGORY.ts

Any tips on what to do to find the cause of these cases?

import { CategoryInitializer } from "../../lib/commandhandler/mod.ts";
// [1] Removing the "Dummy" source initializer and any references fixes the issue
import { Dummy } from "../../lib/sources/dummy.ts";
import { TrollegleSources } from "../../trollegle.ts";

export default new CategoryInitializer<TrollegleSources>({
  name: "Main",
  description: "The main command category every user can use",
  prefices: ["/"],
  async permitted(user) {
    // Check [1]
    if (!(user.connection instanceof Dummy))
      return await user.connection.send("no"), false;
    return true;
  },
});

import { CategoryInitializer } from "../../lib/commandhandler/mod.ts";
// [1] Removing the "Dummy" source initializer and any references fixes the issue
import { Dummy } from "../../lib/sources/dummy.ts";
import { TrollegleSources } from "../../trollegle.ts";

export default new CategoryInitializer<TrollegleSources>({
  name: "Main",
  description: "The main command category every user can use",
  prefices: ["/"],
  async permitted(user) {
    // Check [1]
    if (!(user.connection instanceof Dummy))
      return await user.connection.send("no"), false;
    return true;
  },
});

It is worth noting the topmost contents of dummy.ts as well:

import { cli } from "../../trollegle.ts";
import CLI, { CLIEvent } from "../cli/mod.ts";
import {
  CoreEvents,
  BaseDummySource,
  EndReason,
  CoreSourceEvents,
  ConnectOptions,
} from "./types.ts";

// ...

import { cli } from "../../trollegle.ts";
import CLI, { CLIEvent } from "../cli/mod.ts";
import {
  CoreEvents,
  BaseDummySource,
  EndReason,
  CoreSourceEvents,
  ConnectOptions,
} from "./types.ts";

// ...

assuming that "../../trollegle.ts" is the entry file

8 | import { Dummy } from "./lib/sources/dummy.ts"; It imports it directly

Although then, weird how everything else that imports anything from [entryfile] doesnt come up with the issue

dummy.ts among other files regarding various initializers go before CATEGORY.ts Maybe it's not possible to import from a file that directly imports said file

Nope, I'd argue it might even be the last one

What's considered a "circular dependency"

That's why I wanted to ask, because I already do something similar (excluding CATEGORY.ts) which does not produce the error Okay, what about this:

Okay that may be useful

Right, but how would I do the following: have an entry file declare some useful things, such as class initializations having the entry file import (execute) other files which require importing of those useful things from the entry file Also, since these are dynamic imports, can't use deno info Okay, turns out it was because I was importing from the entry file while it had a top-level await operation hanging

actually its just the "await completion of method init of Trollegle<TrollegleSources>"

yeah

Unknown User•2y ago

its basically "wait for the initializer to complete initializing a thing which initializes a thing that initializes another thing which imports the entry file" "which is waiting for the initializer to complete <ref *1>"

it would be better if it were just like

i doubt they'd just put a dumb error with 0 verbosity if they could make it include some information
