Getting 400 error code without specific detail in getInfo Api

I'm getting this error:
```DetailedApiRequestError (DetailedApiRequestError(status: 400, message: No error details. HTTP status was: 400.))```

when trying to find scopes granted to a user using this code:

```
final oauth2Api = Oauth2Api(client);

final tokenInfo = await oauth2Api.tokeninfo();

final grantedScopes = tokenInfo.scope;
```

I verified that the client is not null and I'm fetching it using [this package](https://pub.dev/packages/extension_google_sign_in_as_googleapis_auth).

This error is very unpredictible and happens once in a while but it's breaking a major flow in our app. Please guide me what I'm doing wrong or how to debug it.
