Xray.cloud posting test results. ["error": "Error creating Test Execution]

[Alexander Brandhaug]

I'm trying to post test-results to a Jira project using Xray Cloud.

I'm getting the response when hitting: POST https://xray.cloud.getxray.app/api/v1/import/execution/nunit/multipart

"error": "Error creating Test Execution - Issue create failed! - issuetype: Enter a issuetype"

My info.json looks like this: 

{
"fields": {
"project": {
"key": "IUV"
},
"summary": "Automatic result import from automation run",
"issuetype": {
"name": "Test From Postman"
}
}
}

Anyone who can contribute to what I'm doing wrong in the json-file? (I assume that Im missing something).

Thanks alot!
