Hi @zyy-hw! I'm Dosu and I’m helping the dify-official-plugins team.

This error is most likely caused by the plugin or backend returning None where an iterable (like a list or dict) is expected—often when parsing the model's response or handling workflow variables. For Qwen models, known issues include non-streaming mode incompatibility, missing expected fields in the response, or the backend closing the connection prematurely during non-streaming requests. Double-check that your backend supports non-streaming requests and returns the expected response structure (especially fields like choices) source. Also, ensure your plugin configuration matches the backend's requirements, and consider debugging the workflow to trace variable values before plugin invocation source. If possible, try disabling streaming or switching to a market-provided OpenAI-API-compatible plugin for better compatibility source.

To reply, just mention @dosu.
