Hey there! I'm trying to test a simple EL from mongo to a local postgres db.

meltano invoke tap-mongodb > output.json

works properly If i run

meltano run extractor tap-mongodb target-postgres

I get an error: "Error: Block extractor not found" this is my loaders section: loaders: - name: target-postgres variant: meltanolabs pip_url: meltanolabs-target-postgres config: user: sqlmesh database: sqlmesh host: localhost port: 5432 What could be the issue? I can properly connect to my db with dbeaver .

You probably want just

meltano run tap-mongodb target-postgres

(with no

extractor

in that command)

that works, thanks a lot! If i may ask, what is the extractor, when should i use it? because meltano run alone seemed to run into the same error so maybe its used by default

The

meltano run

command (docs) expects a list of plugin names after it, and “extractor” is not a known plugin name to your meltano project. I believe that’s what the error message

"Error: Block extractor not found"

is saying.

I see Matt, thanks a lot. Have a great day!
