Gsuite package error on send mail

studio
#1

I’m trying to use package Gsuite developed by UiPath.
On the activity send mail I get the following error :

Google.GoogleApiException: Google.Apis.Requests.RequestError
Bad Request [400]
Errors [
Message[Bad Request] Location[ - ] Reason[failedPrecondition] Domain[global]
]

I’m using service account with JSON file.
Anyone has ideas about what to check about the service account setup ?

Thanks
