Hello everyone, I'm new to Meltno and I'm trying to use the extractor tap-csv, but whatever config I try, I always end up with the same error :
Copy code
Cannot start extractor: Catalog discovery failed
Any idea ? The command 'meltano invoke tap-csv --help' run and print : 2022-07-25T120537.132977Z [info ] Environment 'dev' is active Usage: tap-csv [OPTIONS] Execute the Singer tap.
