@Tofuzhu Hello there! I'm here to assist you with bug fixes, questions, and becoming a contributor. Let's squash those bugs together! 😉

The 404 error you're encountering when submitting the API key for the Gemini model suggests that the model "gemini-pro" is either not found or not supported for the "generateContent" method in the API version v1beta. Here are a few steps you can take to resolve this issue:

  1. Verify Model Availability: Ensure that the Gemini model is available and supported for the API version v1beta. You can check the list of supported models and their methods in the api/core/model_runtime/README.md file of the Dify repository [1].

  2. Check API Version: Confirm that you are using the correct API version. The error message indicates a potential mismatch between the model and the API version.

  3. List Available Models: Use the "ListModels" API call to retrieve the current list of available models and their supported methods. This will help you verify if the Gemini model is listed and supported for your intended use.

  4. Configuration Check: Ensure that the configuration for the Gemini model is correctly set up. The configuration details, such as model type and features, are defined in a YAML file [2].

If the issue persists after these checks, there might be a need to update the model configuration or consult the documentation for any recent changes in model support.

I've checked the availability of the api key and my same gemini key, works fine in the Cherry studio client, so it shouldn't be a key issue. There really isn't anything else I can troubleshoot with cloud dify.

The issue arises because Dify uses the gemini-pro model to validate your API key, but this model has been deprecated. It will be resolved in the upcoming version.

I deployed it with docker, and this error occurred during binding. I tried to modify it, but it did not achieve the result I expected. I hope this problem can be solved in the next version! Thanks!

I have also faced the same issue first I was using the "gemini-pro" model but when I changed it to "gemini-1.5-flash" this resolved my issue.
I think this was due to the new update because this was working when I first implemented it in Oct 2024.

Hi, I'm using Dify Cloud and the problem persists:

I'm not currently using Gemini in any chat. Is there any forecast for a definitive fix? Why does Dify validate the list of models when registering the API Key? @hjlarry

  2. Remove the Gemini plugin
