Workflow "JSON not Valid" blocking workflow from running

Hi all - the startTrigger for a workflow is showing "Invalid JSON" for something which is, as far as I can tell, perfectly valid JSON. This prevents the next steps from running. Am I missing something here?


Perhaps just a visual bug?

I fully logged out of everything waited a bit and logged back in and it is working now.

Would be nice to know what happened, but I'll close this for now.
