How do I upload a cucumber JSON results file to my Zephyr Scale project?

So I have a project in Zephyr Scale.  I have my JSON results file from the execution of my cucumber tests.

I've followed the documentation and attempted to upload my results file via a POST from Postman (as a test) and I'm getting no response from the server.

The url is https://api.zephyrscale.smartbear.com/v2/automations/executions/cucumber?projectKey=QAT&autoCreateTestCase=true and QAT is the name of my Zephyr project.

The Authorisation is by Bearer Token that I generated from Zephyr and works for other API calls.

I have set the body type to form-data and have the following parameters:

file - report.json

type - application/json

When I run it, I get no response.  When I run the same thing from curl I get a response of 

no matches found: https://api.zephyrscale.smartbear.com/v2/automations/executions/cucumber?projectKey=QAT

I know the QAT project exists because if I run https://api.zephyrscale.smartbear.com/v2/automations/testcases?projectKey=QAT I get a response

I tried the same with a junit.xml type file and still get the same issue.  Any ideas where I' going wrong here?
