Dify version

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

When using Google's official API in Agent mode, I can successfully retrieve the knowledge base. However, with the same Agent setup, switching to an OpenAI-API-compatible approach (e.g., Gemini integration) fails to retrieve the knowledge base

Compatible API Result

✔️ Expected Behavior

It is expected that both methods can retrieve the knowledge base normally

❌ Actual Behavior

OpenAI-API-compatible did not work for me

I found a similar open issue titled "OpenAI-API-compatible methods cannot retrieve knowledge bases" [1]. The suggested solution for this issue is to consider switching to using either the Qwen or Deepseek AI model instead of the problematic model, as there might be incompatibility issues between certain AI models and the RAGFLOW system, which can result in malformed queries. Additionally, ensure there is no OpenAI service outage by checking their status page, as this could also affect the retrieval process.

Furthermore, it is important to verify that the API Key and endpoint URL are correctly set in your configuration. Also, ensure that the model type and other parameters such as context size and completion mode are appropriately configured according to the requirements of the OpenAI-API-compatible provider you are using [2].
