hub.knime.com%20Chat%20Model/2.5%20-%20%20Retrieval%20Augmented%20Generation%20ChatApp~nBhjtxPFqFxnqGst/most-recent)

You can see, that there is an error regarding the API key at the “Vector Store Retriever”: Vector Store Retriever #21: ‘Error retrieving credentials for identifier: api_key’

When I connect the node directly in the top level, it works fine. If it is embedded in the component I receive the error again:
