What could be the problem here? My meltano version is 3.7.8 Thanks in advance!

Do you have an empty mapping in your

meltano.yml

somewhere? I'm able to reproduce the same error by removing all plugins, but leaving the

plugins

key:

Thanks, I found an empty file that was causing the issue.

Hey @Alex You, do you mean an empty file you included in

include_paths

?

Yes, I had an empty

.yml

file in the directory I had set in

include_paths

that I removed and fixed this issue
