Describe the Bug

AKA we should support self defined WorkerEntrypoint better.

Consider this worker

// ./src/server.ts
import { WorkerEntrypoint } from "cloudflare:workers";

export class MyWorker extends WorkerEntrypoint {
  someMethod() {
    return "hello " + Math.random();
  }
}

export default {
  async fetch(request: Request, env: Env, ctx: ExecutionContext) {
    return Response.json(await env.MyWorker.someMethod());
  }
}

with this wrangler.toml:

name = "example-worker"
main = "src/server.ts"
compatibility_date = "2025-01-28"

[[services]]
binding = "MyWorker"
service = "example-worker" # this shouldn't be necessary
entrypoint = "MyWorker"

2 problems here:

• service = "example-worker" shouldn't be ncessary since it's in the same worker. it should default to the main worker. but removing that line causes validation to fail.
• when running wrangler dev, I get this output

That seems wrong, since it connects to itself successfully. Thankfully the worker still functions.

Please provide any relevant error logs
