Welcome to Stack Overflow. :)
Yes, to diagnose the issue exactly we would need your complete template but based on the error it just looks like [incorrect segment length][1] issue i.e.,
in general a ROOT resource type must have segment length one greater than its resource name i.e., if your ROOT resource type is something like "type": "Microsoft.xxxxxxx/yyyyyyy/zzzzzzz" then it's name should be something like "name": "aaaaaaa/bbbbbbb"
and a NESTED resource type must have identical number of segments as its resource name i.e., if your NESTED resource type is something like "type": "Microsoft.xxxxxxx/yyyyyyy/zzzzzzz" then it's name should be something like "name": "aaaaaaa/bbbbbbb/ccccccc" For more information, please refer [this][1] document.
Source of the above information is [this][2] Stack Overflow thread.
Hope this helps! Cheers!
