Steps to reproduce

✔️ Expected Behavior

When selecting the tongyi series model, blocking output is supported.

❌ Actual Behavior

{ "code": "completion_request_error", "message": "[tongyi] Server Unavailable Error, parameter incremental_output only support stream call", "status": 400 }

[dosubot[bot]]

The error you're encountering with the Tongyi model in blocking mode is due to the incremental_output parameter, which only supports stream calls. This is a known issue where the _generate method in the TongyiLargeLanguageModel class is designed to handle responses with incremental_output=True only when stream=True. When invoked in blocking mode (stream=False), this parameter is not supported, leading to the error ^[1].

There are similar discussions on this topic that might provide additional insights:

1. When using the API, the blocking mode is not working ^[2].
2. Help：agent not support blocking mode in restful api，why? ^[3].

These discussions are still open and might not have a definitive solution yet. You might want to follow them for updates or potential workarounds.
