Reversion: Form trigger does not show form

[FWCorey]

Describe the problem/error/question

Updated n8n to version Version 1.108.2 an encountered this error > https://community.n8n.io/t/form-trigger-no-form-appears-bug/77247
closing the n8n tab and reopening it from Powershell also does not correct the issue.

What is the error message (if any)?

Received request for unknown webhook: The requested webhook "b8cb006d-ad7c-4500-818a-1e08d027041a" is not registered.

Hey @FWCorey,

Are you trying the test url or the production url?

[FWCorey]

I thought Test/Production etc was an Enterprise feature?
In any case I'm using the default n8n form trigger node with 2 fields and I'm on a Community license.

Hey @FWCorey

There should be 2 URLs for the form a production url and a test url. Which one are you trying to load?

The environments feature is for paid plans but it doesn't impact the URLs for the nodes.

[FWCorey]

I didn't enter the URL it was automatic when I added the node. It worked before the update.
Looks like the test url is being used.

[FWCorey]

I also tried deleting the node and recreating it after restarting n8n to no avail.

Hey @FWCorey,

Can you maybe record a video of what you are doing as I am not able to reproduce this.

[FWCorey]

Maybe we could use Meets, Zoom or Discord so I can share screen? It will be more interactive so we can troubleshoot it faster.
I'm guessing this may be something dependent on my configuration as a fairly new n8n user. Maybe a missing Environment Variable a more experienced AI agent user would have previously configured.
