Recording testcase via REST API

Hey guys,

I'm currently looking at how to get our pipeline unit tests recorded in Spira.

I'm using the test-runs/record endpoint, and it seems to be working, but I have a question.

I want to store the 'dump' from the test tool (Jest) somewhere. One option is to use the

'RunnerStackTrace' field. But another option is to add it as an attachment. However, it is not entirely clear how to do this based on the documentation provided.

On the one hand, there is the Documents endpoint that should allow me to associate an artifact with an attachment. On the other hand, the test-runs/record endpoint has an argument AutomationAttachmentId which suggests I can directly attach an already existing Document to the created Test Run. However, the JSON skeleton in the documentation lists "AutomationAttachmentId":null, suggesting you  need to provide a string instead of an artifact ID. How is this supposed to work?
