👋 im running into

ValueError: source produced an invalid metadata work unit:

when i am trying to a write a custom ingestion script using the python library. is it possible to get a more specific exception msg that provides info on which part of the mcp is invalid?

I hear you... I also find this annoying and the best way I could find without entering a debugger is to manually call

validate()

on aspects that I creating. This way you'll know which aspect is wrong, but you won't know which attribute. But this will narrow your search. Would be happy to hear if there is a better way!

@modern-monitor-81461 Should the

validate()

be printing out a value…? I added it but am not seeing anything different

No, it will return a boolean indicating if your aspect is valid or not.

Right, to get the exact issue validate hit currently you would have to step through and see where it hits a false point. There aren't currently printouts or error messages passed up that indicate what the exact error was in the Python emitter.
