I could really use some help getting my Global Cache Flex to send IR commands. I have it working just fine from Postman, but it seems like no matter how I set up my network resource, it just errors out telling me with a -1/-14002 message in the error log. I believe this is indicating that the end tag is malformed. I also have multiple other network resources that send PUT requests to a Bond Bridge, and they work just fine. I can create new ones of those at will with success every time.
I have attached screenshots from the Postman Console, one of my Bond Bridge network resources (PUT to 10.0.0.221) that works fine, and my GC Flex test network resource (POST to 10.0.0.225) that errors. Note that the GC Flex just returns an empty 200 OK message to Postman, and it does send the IR signal. I've also tried sending just the minimal set of headers for the GC Flex request like in Postman. This version is when I tried recreating all the headers that are working for the Bond Bridge network resource. Honestly, I've tried dozens of different options. I know other people not only have this working but say it's simple. So, I must be missing something dumb.
Any help is appreciated.
