I've started developing a tap called

tap-growthbook

using the Meltano SDK. When testing without meltano it runs fine, but then when I invoke with

meltano run

via

uv run

I get a discovery related error, and I don't know how to debug it. Here's the error:

Can you run

meltano invoke tap-growthbook --discover > catalog.json

and inspect the resulting file? We're looking for a line that might throw off the JSON parser.

Yes it's producing this odd double object at the top of the file:

{'$schema': '<http://json-schema.org/schema#>', 'type': 'object', 'properties': {'id': {'type': 'string', 'description': 'Unique identifier for the experiment'}, 'name': {'type': 'string', 'description': 'Name of the experiment'}}}
{'$schema': '<http://json-schema.org/schema#>', 'type': 'object', 'properties': {'id': {'type': 'string', 'description': 'Unique identifier for the experiment'}, 'name': {'type': 'string', 'description': 'Name of the experiment'}}}

    {
      "tap_stream_id":"experiments",

      "key_properties":[

      ],
      "schema":{

          },
          "name":{

      },

      "metadata":[

          "breadcrumb":[
            "properties",
            "id"
          ],
          "metadata":{
            "inclusion":"automatic"
          }
        },
        {
          "breadcrumb":[
            "properties",
            "name"
          ],
          "metadata":{
            "inclusion":"available"
          }
        },
        {
          "breadcrumb":[],
          "metadata":{
            "inclusion":"available",
            "selected":true,
            "selected-by-default":true,
            "table-key-properties":[
              "id"
            ]
          }
        }
      ]
    }
  ]
}

Glad you figured it out!
