Reproduction Steps

from mistralai import Mistral

client = Mistral()
client.chat.complete(
    model=model_name,
    messages=messages,
    stream=True
)

Expected Behavior

Expacted response:
data=CompletionChunk(id='46230b1e187746a386e70340b2ab9297', model='mistral-small-latest', choices=[CompletionResponseStreamChoice(index=0, delta=DeltaMessage(role='assistant', content='', tool_calls=Unset()), finish_reason=None)], object='chat.completion.chunk', created=1735207005, usage=None)

Additional Context

But this error is shown:
mistralai.models.sdkerror.SDKError: Unexpected response received (code: 200, type: text/event-stream; charset=utf-8): Status 200

I know that client.chat.stream() exists, but client.chat.complete() has also a param called stream, meaning that it could be used to stream a response.

Suggested Solutions

No response
