Every time I try to activate my workflow I get a obj error

Questions

I keep getting this error when I try to activate my workflow:

Workflow could not be activated:

There was a problem activating the workflow: “Unknown alias: obj”

Everything is running fine when I test it, and I have now been debugging for a while, but still I have no idea where the problem lies, so I am assuming it is a bug.

I have tried all the usual tweaks like debugging, putting it into a new workflow, clearing my cache, etc. I have run deep analysis on my JSON with Claude, o3 and Gemini. No one can find the error.

It is running in the n8n cloud. It was working fine, all of a sudden it turned itself inactive and the I can no longer activate it.

Any smart people in here with a good idea?
