Gemini though Mosaic Gateway

[roman_belkin]

I am trying to configure the Gemini Vertex API in Databricks. In simple Python code, everything works fine, which indicates that I have correctly set up the API and credentials. 

Error message: 
{"error_code":"INVALID_PARAMETER_VALUE","message":"INVALID_PARAMETER_VALUE: Failed to generate access token for Google VertexAI. Please check the private key for the external model gemini-pro."}

I tried using different model names, but I didn't have any luck.

No, it seems they gave up

With support from a helpful Databricks employee, we found out that the problem was that the `private_key` / `private_key_plaintext` field needs to be the entire JSON object that GCP creates for the service account not just the private key string from it as the documentation lead us to believe
