Description

Consider the countries sample in this repo.

1. Generate the Singer catalog for the tap:

   $ poetry run python samples/sample_tap_countries --discover > countries.catalog.json

2. Create a stream maps config for the tap. This one creates slugs for both the continent and country name:

   $ jq < countries.stream_maps.json
   {
       "stream_maps": {
           "continents": {
               "slug": "str(name.lower().replace(' ', '-'))"
           },
           "countries": {
               "slug": "str(name.lower().replace(' ', '-'))"
           }
       }
   }

3. Run the tap with the generated catalog and stream maps config:

   $ poetry run python samples/sample_tap_countries --catalog countries.catalog.json --config countries.stream_maps.json > countries.singer.jsonl

   This should work as expected.

4. Now, open countries.catalog.json and edit it to deselect the countries stream

   $ jq '.streams[1].metadata[-1]' < countries.catalog.json
   {
     "breadcrumb": [],
     "metadata": {
       "inclusion": "available",
       "selected": false,   <----- this right here needs to be 'false'
       "selected-by-default": true,
       "table-key-properties": [
         "code"
       ]
     }
   }

5. Run the tap again:

   $ poetry run python samples/sample_tap_countries --catalog countries.catalog.json --config countries.stream_maps.json > countries.singer.jsonl

   You'll end up with

   singer_sdk.exceptions.StreamMapConfigError: Invalid key properties for 'countries': [code]. Property 'code' was not detected in schema.
