Create TEMPO Worklog via REST including worklogAttributes

[flow8282]

Hi,

I'm using the REST API to create worklogs, which is working fine, except that I'm not able to submit worklogAttributes successfully.

I've tried both ways from API Version 7.12 and 8.

Thats my JSON in API 7.12:

    "worklogAttributes": [{
        "value": "DE",
        "key": "_Location_",
    }]

And here in API 8:

    "workAttributeValues": [{
        "id": 967974,
        "value": "DE",
        "worklogId": 0,
        "workAttribute": {
            "id": 6,
            "key": "_Location_",
            "name": "Location"
        }
    }]

Since the documentation is not 100% cclear, I want to ask if I miss something crucial or is there another mistake?

Here's how a worklog looks when it's entered in tempo directly and viewed via REST API:

Thanks for any help!
