“I have checked the logs but don’t have more details on why the scheduled API workflow isn’t launching. I’m not sure why this is happening. Has anyone tried triggering it from a table instead of a repeating group?”
One cause of this issue I have seen is where the issue checker (the red error count in the editor) doesn’t detect an error, but there is an error somewhere (eg in an arbitrary text).
So this error sort of means “error in my generated code” and you need to open up all expressions and check they aren’t red to find any errors.
