@dev2049 which do you mean, this one: tests/integration_tests/vectorstores/test_weaviate.py ? this integration test also add cassettes files

this one, seems like it's 200k lines tests/integration_tests/vectorstores/cassettes/test_weaviate/TestWeaviate.test_similarity_search_without_metadata.yaml

fixed! The cassette was picking up the weaviate initialisation in the docker container, so after making sure the container was up and the weaviate instance had processed some jobs I re-ran the tests and saved the new cassette. Thanks for spotting that @dev2049 !
