Server Error - Cant save or archive a workflow

Questions
1

Hi everyone,
bit of a strange error and I’m not sure where to look.

Describe the problem/error/question

I have this one buggy / broken workflow that I can’t change, save, rename, deactivate or do anything else with. Even though it’s active, it does not run.

I have made a copy of it and it works perfectly.
But the broken original is still there.

What is the error message (if any)?

“The server had an error while processing your request. Sorry about that!” (see screenshot below)

@stefan_meyer yes, but I’ve just updated my n8n community version to the latest one. After that it randomly worked.

Thanks for the details. This looks like a corrupted workflow entry—especially since the copy works fine and this one can’t be edited, saved, or deactivated. It’s likely a DB-level issue (common with SQLite on self-hosted setups).

You can:

  • Keep using the working copy (recommended).
  • Or if you’d like to clean it up, I can help you safely delete the broken workflow directly from the database.
