Steps to reproduce

I installed azure openai plugin 0.0.8, when using o3-mini modle, stream always set to false in http request, but the plugin is expecting stream response.

I found a similar discussion thread titled "azure openai api Stream options setting" which is currently unsolved ^[1].

Regarding your issue, the TypeError in the _handle_invoke_result_stream method suggests that result.delta.message.content is a list, but the code is attempting to concatenate it as if it were a string. To resolve this, ensure that result.delta.message.content is indeed a string before concatenating it. You might need to convert or join the list elements into a string format.

Additionally, the stream parameter in the HTTP request is set based on the response_mode. If response_mode is "streaming", stream should be set to True; otherwise, it is set to False <sup>[[2]](https://github.com/langgenius/dify/blob/main/sdks/python-client/dify_client/client.py)</sup><sup>[[3]](https://github.com/langgenius/dify/blob/main/sdks/nodejs-client/index.js)</sup>. Ensure that the response_mode is correctly set to "streaming" if a stream response is expected.
