Google API failed to generate a key

Error

Google API failed to generate a key.

Why this happens

Neural Inverse couldn't obtain a valid access token from your Google credentials. This applies to Google Vertex AI (not Gemini API — they use different auth).

Fix

For Google Gemini (aistudio.google.com)

This error shouldn't appear for Gemini. If it does, you may have selected the wrong provider:

Open settings
Select Google Gemini (not Vertex AI)
Enter your API key from aistudio.google.com

For Google Vertex AI

Vertex uses Application Default Credentials:

Install gcloud CLI
Authenticate:
```
gcloud auth application-default login
```
Set project and region in Neural Inverse settings

Verify credentials:

gcloud auth application-default print-access-token

Common causes

GOOGLE_APPLICATION_CREDENTIALS env var points to a deleted/moved file
Service account key expired
ADC token expired — re-run gcloud auth application-default login
Wrong project ID in settings
