This is a known issue caused by stricter type validation for prompt_messages.content.type in Dify 1.8.1 and dify_plugin SDK versions >=0.0.1b74. To resolve it, try upgrading to the latest vllm plugin (v0.1.4), which includes a fix for this compatibility problem. If you still encounter the error, you can work around it by editing the plugin's requirements.txt to pin the dify_plugin SDK version below 0.0.1b74 and reinstalling the plugin locally. More details and the relevant commit are available here.

If you are running in an offline/air-gapped environment, you may also need to manually migrate provider credentials and models in your database, as automatic migration is skipped in these setups. If you need guidance on this, let me know your environment details.

To reply, just mention @dosu.
