Initialize the SDK for
documentation on how to authenticate the Admin SDKs with a certificate
credential.

No Firebase project was found for the credential used to initialize the Admin SDKs. See Add Firebase to your app for documentation on how to generate a credential for your project and use it to authenticate the Admin SDKs. |
auth/insufficient-permission |
The credential used to initialize the Admin SDK has insufficient permission to access the requested Authentication resource. See Add Firebase to your app for documentation on how to generate a credential with appropriate permissions and use it to authenticate the Admin SDKs. |
