# Why does Google connect return a google\_no\_datasource warning?

The `google_no_datasource` warning means the connected Google account has **no devices or health data sources attached**, usually because the user picked the wrong account or doesn't use Google Fit.

**Deauthenticate the user** via the `deauthenticateUser` endpoint and ask them to reconnect the correct account. Use the `reference_id` in the payload to identify them.

To detect the same wearable account linked to multiple of your users, call the `/athlete` endpoint and compare the `provider_user_id` field, which uniquely identifies the underlying account.
