Symptoms

• Non-streaming succeeds but streaming appears blank.
• Raw event data contains chunks the application ignores.

Likely causes

• The parser assumes one provider’s SSE shape or treats an early metadata event as completion.
• A proxy buffers, rewrites, or closes text/event-stream responses.

How to diagnose

• Capture a redacted raw stream and inspect event order.
• Confirm Content-Type is text/event-stream.
• Compare the same request with stream false.

Fixes

• Parse the endpoint’s documented delta events and terminal marker.
• Ignore metadata-only chunks without ending the response.
• Disable proxy buffering for SSE when required.

How to verify

The client accumulates content through the terminal event and matches the non-streaming answer shape.
