Not able to use Gemini tuned model form Node JS

Hi All,

Is it possible to access Gemini Tuned model from the server? It seems that it requires OAuth2. When I tried to use the Service Account JSON for the authentication then I am getting the error message : “Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential‘.

If I use client_secret.json from OAuth2 Client ID then I get the error: “Missing client_email”

If anyone has successfully used Gemini Tuned Model from the server side especially Node JS then any help will be appreciated.

Regards,

Kapil
