Webhooks not working in version 1.94.1

[spitdm]

Bug Description

I've upgraded n8n from Version 1.93.0 to version 1.94.1. I use n8n with Docker.
After the upgrade, it was no longer possible to register a new webhook, whether in manual mode (Execute Workflow) or in automatic mode. I tested the newly created webhooks several times with Postman, and I always got the message:

{
"code": 404,
"message": "The requested webhook "c9674854-be3d-4f34-9985-53a57ffaa7eb" is not registered.",
"hint": "Click the 'Execute workflow' button on the canvas, then try again. (In test mode, the webhook only works for one call after you click this button)"
}

Webhooks that existed before the upgrade continued to work without issues. Now I've downgraded n8n to version 1.94.0, and all webhooks are working as expected again.

I'm not sure if this is a bug or if I've missed something.

To Reproduce

1. Create a new Webhook
2. Klick "Execute Workflow"
3. Test to connect to the webhook via Postman
4. Error Message:
   {
   "code": 404,
   "message": "The requested webhook "c9674854-be3d-4f34-9985-53a57ffaa7eb" is not registered.",
   "hint": "Click the 'Execute workflow' button on the canvas, then try again. (In test mode, the webhook only works for one call after you click this button)"
   }

Expected behavior

1. Create a new Webhook
2. Klick "Execute Workflow"
3. Test to connect to the webhook via Postman
4. Connection succesful

Hey @spitdm,

We have created an internal ticket to look into this which we will be tracking as "GHC-2240"

Thanks for reporting this issue! We’ve attempted to reproduce the problem, but unfortunately, we weren’t able to replicate it. It’s possible there was some environmental or other variable that prevented us from seeing the same behavior.

Can you try using 1.95 and let me know if you see the same issue there?

If you’re still encountering this issue, please provide any additional details or steps to reproduce it, and we’d be happy to investigate further. Thanks for your understanding!

Thanks for your response!

Now I've upgraded n8n to version 1.94.1 again. And now it works without any issues!
I don't know what was wrong yesterday. Maybe there was an issue with the container or Docker itself!
