I have created an automation X which is working fine using my account and I have taken a copy of that Automation to run it in other user workspace. Automation is working fine for one user and not working for other user for the same settings and accesses.
Please refer to the attaches screenshot and help me to fix the issue.
I see that you are getting a 403 permission error. Maybe the user doesn't have the proper permission. Could you please crosscheck the permission of the user and let us know?
