Cloud scheduler HTTP function "status": "UNAUTHENTICATED". Google app engine

Question

We have a simple app in Google App Engine (python 3.6). We are trying to trigger a funciton (url) using Cloud scheduler. Using the console we have trigger that has the following frequency -

 1 0 * * * (America/New_York)

The target is URL : https://project-name.appspot.com/url

When we click "Run Now" on the console we get the following error in the logs -

"status": "UNAUTHENTICATED", "url": "https://project-name.appspot.com/url", 
"@type": "type.googleapis.com/google.cloud.scheduler.logging.AttemptFinished", 
"jobName": "projects/project-name/locations/us-central1/jobs/url", "targetType": "HTTP"

Please help.

I ensured that the service account [e-mail] is added to IAM.

Answer 1

According to the documentation here we need to post the entire URL.

But in reality just post the relative url. That is just do /url_extension
