Failed dependecy for the firewall policy POST method

Hello Community,

I am attempting to POST an additional firewall policy using the API method. Getting back a 424 Failed dependency. I have always included the API key, and have also tried optionally setting vdom,  datasouce, and with_meta but none resolved the issue. Although they are all not checked in the screenshot, they each have been tried. Here is a screenshot from Postman.

Body is JSON format, as follows

{     "name": "TEST",     "srcintf": [       {         "name": "lan"       }     ],     "dstintf": [       {         "name": "lan"       }     ],     "action": "accept",     "srcaddr": [       {         "name": "all"       }     ],     "dstaddr": [       {         "name": "all"       }     ],     "schedule": {       "q_origin_key": "always"     },     "service": [       {         "name": "ALL"       }     ],     "nat": "enable"  }

Any thoughts on what this could be depending on?

Appreciate it
