If GET works but POST does not, there may be something wrong with the request variables in the script. Make sure the code in your script generating the request variables (request_vars) matches the code in the example.

You can add a line to the relevant section of the script to inspect the request variables in the Postman console: 

// If the request includes a payload, included it in the request variables
var request_vars = (http_verb == 'GET'||http_verb == 'DELETE') ? 
http_verb + epoch + resource_path : http_verb + epoch + request.data + resource_path;
console.log(request_vars)

After saving the change to the pre-request script, open the Postman console then send the request.

request_vars for a GET request is just GET+timestamp+resource_path like this: 

GET1553268441890/device/groups

request_vars for a POST request must include the body data between the timestamp and the resource path and so should look like this: 

POST1553267947762{"name":"Postman"}/device/groups

I hope this helps. If not, feel free to share your POST request and I'll be happy to take a look.
