Why I Am Getting Error 'Failed to save settings. Returned status: 400' After Upgrading To Ansible Tower 3.7.x ?
Issue
After upgrading to Ansible Tower 3.7.x, I'm getting the following error when I try to save any settings from the UI or API.
Failed to save settings. Returned status: 400
In the /var/log/tower/tower.log of the Ansible Tower nodes, I only see the following error.
