Hello @mbpz! I'm Dosu, a bot here to help you with bugs, questions, and contributing to the project. While you wait for a human maintainer, feel free to let me know how I can assist you!

I found some relevant information that might help you resolve the 500 INTERNAL SERVER ERROR in Dify version 1.2.0 when using a self-hosted Docker environment.

  1. Optional Parameters: Ensure that all optional parameters in your requests are explicitly set with values. Leaving them blank can cause errors like 'TypeError: object of type 'NoneType' has no len()' [1].

  2. Alternative Endpoints: If you are accessing the '/v1/messages' endpoint and encountering issues, consider using the '/v1/chat-messages' endpoint as an alternative [1].

  3. Code Fix: You can apply a fix from the main branch by modifying the code in your Docker container. This involves changes related to handling the retriever_resources field [2].

  4. Model Providers Configuration: If the error occurs when configuring model providers, try modifying your docker-compose.yaml file to add or increase the PLUGIN_MAX_EXECUTION_TIMEOUT value. Also, consider removing any proxy settings from the plugin_daemon configuration or reinstalling the specific model provider plugin [3].

These steps should help you address the internal server error. If the issue persists, reviewing the server logs for specific error messages can provide more insight into the underlying problem.
