Hi @systemaddict, this looks scary indeed and I am very sorry for the trouble. Does this happen only with certain workflows or all of your workflows? Any helpful error messages in your browser console?
I’ve seen this on an instance from one of my clients as well. This is an older version.
There were some nodes on that with issues. Since the issue with the node was fixed I haven’t seen it happen anymore.
Do you have any community nodes in this workflow @systemaddict ?
No, I don’t think so. But surely a lot of nodes that weren’t touched for a long time. But now you say it, I think I did see the same error when I tried to import a full community workflow through copy/paste (the github backup flow), but now I can’t reproduce it again.
