workers-sdk: 🐛 BUG: Unable to run wrangler dev since version 3.19.0

Which Cloudflare product(s) does this pertain to?

Wrangler core

What version(s) of the tool(s) are you using?

3.26.0

What version of Node are you using?

20.11.0

What operating system and version are you using?

macOS Sonoma 14.3

Describe the Bug

Observed behavior

Since version 3.19.0 of wrangler was released we’re no longer able to run wrangler dev --remote. It runs, but as soon as a page is viewed the following error is thrown:

✘ [ERROR] Error in ProxyController: Error inside ProxyWorker

   {
    name: 'Error',
    message: 'internal error',
    stack: 'Error: internal error'
  }

Expected behavior

Work as it did in version 3.18.0 and lower.

Steps to reproduce

Due to the code being internal, I cannot provide an exact example. Happy to provide any debug logs that might be useful. The error happens 100% of the time by just running wrangler dev --remote and then opening http://localhost:8787 in a browser (or pressing b).

In case it’s applicable, we have these compatibility settings in wrangler.toml. In saying that though I can replicate by removing both of these.

compatibility_date = "2022-09-01"
compatibility_flags = ["url_standard"]

Potentially worth noting is that I’ve added a console.log in the exported fetch function to see if our worker code ever runs but it doesn’t appear to (or at least the log message is never printed).

Please provide a link to a minimal reproduction

No response

Please provide any relevant error logs

I’ve redacted some parts that I didn’t want public and replaced it with placeholder strings (e.g. <ACCOUNT>).

Thank you for the detailed reply.

If you rename the worker by simply renaming it in wrangler.toml it will create a new Worker, leaving the old one behind.

For future reference, there is no data loss in this method right? Since the bindings remain the same. Its just that the new worker is on a new route - ALL else remains the same. I just have to switch my custom route to the new worker, and I’m done.

If you rename the worker by simply renaming it in wrangler.toml it will create a new Worker, leaving the old one behind. Instead you can rename the Worker in the CF dashboard.

I had a worker called test_worker, which I managed to create using Wrangler (the CF dashboard does not allow this). I logged in the dashboard, clicked on the Worker -> Manage -> Rename Worker. This allowed me to rename the Worker (the CF dashboard would not allow me to put an underscore in the name).

Note that the workers.dev subdomain will change accordingly, in case you rely upon this. Screenshot 2024-03-24 at 16 18 51

Note the warning that is given: Screenshot 2024-03-24 at 16 19 01

Now I would need to go and update the wrangler.toml with the new name so that next time I deploy from Wrangler it does not recreate the old Worker with the underscore in its name.
