Missing Predibase API Key - A call is being made to predibas

Error message

Missing Predibase API Key - A call is being made to predibase but no key is set either in the environment variables or via params

What it means

Credential guard in the Predibase validate_environment: api_key is None and no Predibase key could be found in environment variables, so the Authorization header cannot be built and the request is rejected before sending.
