No response received

Error message

No response received

What it means

generate_streaming finished consuming the Anthropic SSE stream without ever receiving a MessageStart event, so no message object was captured; the guard at the end reports that no response message arrived despite the stream completing.

Solutions

1. Retry the request; a stream that closes without MessageStart is abnormal but often transient
2. Check for API outages or malformed request payloads if persistent
