#1942 bug: Tap fails if stream maps config contains a key for an unselected stream Issue created by edgarrmondragon Singer SDK Version 0.31.1 Is this a regression? • Yes Python Version NA Bug scope Mapping (stream maps, flattening, etc.) Operating System NA 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.
