The error was: KeyError: 'optional'

Hello everyone, I’m writing here to see if you can help me with this issue. I have been trying to solve it for a while without any luck. The problem is with section of variables in the vmanage_device_attachment module. To make sure I had all the variables names correctly, I ran vmanage_device_template_facts. The playbook runs fine when I remove all the variable names that start with “vedgePolicy/” as soon as I add those variables back, I get this error "The error was: KeyError: ‘optional’. I tried to use backslash “vedgePolicy/” to escape the forward slash but that didn’t know. Do you have any suggestions to solve this issue? I appreciate any input, as I have been trying to fix this for a while with no luck yet. thank you.
