Question

Hi I m struggling with setting up tap bigquery with meltano docker I think I m almost there but I m getting ELT could not be completed Cannot start extractor Catalog discovery failed invalid catalog Expecting value line 1 column 1 What I ve found when searching for the error is this <https github com anelendata tap bigquery> Step 2 says Create catalog with this command ```tap bigquery c tap config json d gt catalog json``` I have no idea though how to translate this to my docker container commands

Have you been using the docs at Those are Meltano specific as opposed to the README at which assumes you re running the tap executable by itself without the help of a runner Creating the catalog manually is not necessary with Meltano for example

As for the `Catalog discovery failed invalid catalog Expecting value line 1 column 1` error you can get `meltano elt` to print some additional debugging information when you run it in debugging mode using `meltano log level=debug elt` <https meltano com docs command line interface html debugging> Can you share the error stacktrace that you ll see with that command
