Hey there, @luckymeet! I'm here to help you with bug reports, questions, and becoming a contributor. Let's tackle this issue together!

I found a similar closed issue that might be relevant to your problem. The issue suggested checking the following:

  1. Check Credentials Format: Ensure that the credentials dictionary is correctly formatted and contains all necessary fields. For DeepSeek, the required field is api_key, and there is an optional endpoint_url field for a custom API endpoint URL.

  2. Verify Credentials: Make sure the api_key is up-to-date and has the necessary permissions for accessing the DeepSeek service.

  3. Default Endpoint URL: If you are using a custom endpoint_url, verify that it is correct. The default value is "https://api.deepseek.com".

If the credentials are correct and the error persists, you may need to check with the service provider to ensure there are no issues with the account or service status [1].

To continue talking to Dosu, mention @dosu.

update to 0.15.3 and set the stream delimiter as '\r\n\r\n' if you use OpenAI-API-compatible

After upgrading Dify to version: 1.0, I discovered an OpenAI-API-compatible plugin. I configured it with Aliyun DashScope, and everything worked fine.
