Unable to enable workflow: "Validation Failed"

[wdhdev]

Bug Description

When I attempt to enable my workflow which uses a GitHub trigger, it returns Workflow could not be activated: Validation Failed even though it is valid and was working fine before.

To Reproduce

1. Create a new workflow using the GitHub trigger
2. Use an If statement
3. Use a step to send a message to a Discord channel
4. Workflow should fail

Here is a screenshot of my workflow:

Note: When I run "test step" individually on each step one by one, the workflow works completely as expected, so I am unsure of the issue here as the error message is super vague and provides zero context.

I can export the workflow if needed, but I would rather not do it publicly due to some sensitive information being shown in the export.

I think this issue may be related to #10074.

Expected behavior

The workflow should activate and run fine.

Hey @wdhdev,

We have created an internal ticket to look into this which we will be tracking as "N8N-7990"

Hey @wdhdev,

Did you copy the node from another workflow or did you add it from the node panel?

[wdhdev]

I copied it to another workflow because the original one was not working. Should I try creating them brand new?

@wdhdev yeah, Can you make new ones and try again it could be that for some reason the existing webhook didn't get cleared after a restart.
