I am getting invalid_user: Robot is missing a project number. when trying to access google sheets using the service account created in my project.
I followed the exact steps mention in the URL: https://www.twilio.com/blog/2017/02/an-easy-way-to-read-and-write-to-a-google-spreadsheet-in-python.html
It seems to work for everyone else, and surprisingly I am not able to find any solution on the web.
Accessing the data using oAuth credentials is working good for me, but I want to deploy the code to AWS Lambda and hence need server to server access.
