[Bug]: Incorrect API key provided" when adding Gemini model

[kstij1]

Description

When trying to add the Gemini model by entering a valid API key, the system shows an error message:
“Incorrect API key provided” even though the key is valid and works externally.

Expected Behavior

• The Gemini API key should be verified successfully.
• The model should appear in the “Model List” section after clicking Save.

Current Behavior

• Upon entering the API key and saving, a toast error appears: “Incorrect API key provided.”
• The model is not added to the list.
• Other models (if applicable) work correctly.

Steps to Reproduce

1. Navigate to the API Key management section.
2. Select Gemini from the “Add Model” dropdown.
3. Enter a valid Gemini API key.
4. Click Save.
5. Observe the error: “Incorrect API key provided.”

Possible Causes

• API validation endpoint may be incorrect or outdated.
• Missing or incorrect request headers (e.g., Authorization: Bearer <key>).
• Gemini model integration not aligned with latest API spec.
• Backend may be rejecting keys due to missing environment configuration.

hello @kstij1 I tried replicating the same by using an api key from https://aistudio.google.com/app/api-keys and was able to add a model as shown in the image below:

could you please help me get a little more context as to what might be going wrong on your end?
