Problem submitting response

[boun]

Describe the problem/error/question

I have a self-hosted instance in docker compose. When two different users with two different workflows test a form trigger only the one, that submits first executes the workflow. The second one gets a " Problem submitting response" message with a 404 status code.

I even tried to set the form path manually to

/form-test/mytest1

and

/form-test/mytest2

in oder to have them manually on separate paths, but it seems like the first submission deregisters all others.

What is the error message (if any)?

Problem submitting response

Please share your workflow

First;

Second;

Share the output returned by the last node

Is this problem too trivial or somewhere documented?

Are you saying the two form trigger are put in one workflow?

---

In my case both works fine. Can you give more information about your error?

Hi,

thanks for your reply, and sorry for not beeing clear on my scenario: I have two different users. They both create workflows, that contain a form trigger. Now both users start testing the trigger at the same time. As soon as one user submits, the second one gets the error, that there is a “Problem submitting response”. In the browser console the POST to the webhook is a 404.

So for testing you need two browsers, logged in with two different users, create workflows with form triggers for them and the run both forms in testing mode.
