could not get request metadata for provider: %s from results

Error message

could not get request metadata for provider: %s from results: %+v

What it means

Error emitted by extractGenerativeMetadata when type-asserting the results payload to the provider-specific params type fails (provider recognized, but the result object is not the expected concrete type). This indicates a module returned an unexpected result type — a programming/version inconsistency between the generative module and the replier. The failing provider and the raw results are included.

Solutions

1. Check for a version mismatch between the generative module and the server
2. Report as a bug with the provider name and result shape
