Error: Error sending test message to Cloud PubSub : User not authorized to perform this action. #3593
Description
Hi, I have an issue with gmail.users.watch() function to make system that automatically get new mail from inbox for graduate project.
The error message seems like the user that login google api does not have permissions to access pub/sub service, so I tried to check user inform like below code.
const profile = await this.gmail.users.getProfile({ userId: 'me' });
console.log(profile.data);Through this console, I found login doesn't have any association with this problem.
And I saw someone's solution that adding 'Service Account User' permission to service account will be work. So I tried it too, but same error arose.
I'll attach my code below, so please let me know the correct solution for this.
Thank you.
