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 :

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. Options: --state PATH Use a bookmarks file for incremental replication. --catalog PATH Use a Singer catalog file with the tap. --test TEXT Use --test to sync a single record for each stream. Use --test=schema to test schema output without syncing records. --discover Run the tap in discovery mode. --config TEXT Configuration file location or 'ENV' to use environment variables. --format [json|markdown] Specify output style for --about --about Display package metadata and settings. --version Display the package version. --help Show this message and exit.

Hey @sylvain_gutierrez - did you try using debug mode to see what error is causing discovery to fail? It could be a missing or incorrect config, or maybe it could be failing to actually parse your csv. Debug mode should give you more info though

The debug mode didn't give any more intels... My file is at the good format I suppose ... (I wrote it following the informations in the documentation) : "REGION","NUMMR","ACHLR","AEMM","AEMMR","AGED" "94","63416","3","2012","9","038" "94","63417","4","1997","8","067" "94","63417","4","1997","8","076" "94","63418","6","2010","9","050" In the yaml file I use the config like following : extractors: - name: tap-csv variant: meltanolabs pip_url: git+https://github.com/MeltanoLabs/tap-csv.git config: files: - entity: exemple_csv - path: extract/exemple_csv.csv - keys: - AGED csv_files_definition: - entity: exemple_csv - path: extract/exemple_csv.csv - keys: - AGED

The debug logs should be logging something related to this but you need either

files

OR

csv_files_definition

defined and

csv_files_definition

is a string path to a file that contains the definition. Check out https://hub.meltano.com/extractors/tap-csv. I suspect the tap is failing because youre giving an invalid

csv_files_definition

. Try removing that from your meltano.yml and see if it works

ok, it worked! thanks a lot ! 🙂 I had try it but visibly with a mistake... files don't works for me but csv_files_definition with a json file is good
