"Wait" Forms / triggers no longer working since version n8n 1.123.6

[jorrg]

Just confirming that it is not only me, and AFAIK it is likely related to a recent N8N update.

With the Waitnode configured as form:

Causes infinite wait loop when running

With the error:

Access to fetch at 'https://.../form-waiting/1921' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Any idea how to fix it other than playing in a backup of a previous version?

Follow up question to the N8N cloudron maintainers (maybe @nebulon ?) - any idea on how I could execute on this idea?

Answering my own question again:

Seems to do the trick. Sorry for tagging you nebulon -

Maybe it helps someone else later...

Follow up - with this I get the workflow to run, however, I introduced issues at other places in the app. For example, I can no longer use the "go to subexecution" button

Great you found a solution before I even got to read the thread
And thanks for sharing it in detail here for others also!
