BIM 360 issue "Assigned To"

How can I change "Assigned To" from specific user to unspecified? I used {name: '-'} mainly for my UI which is obviously not enough to be used as input, perhaps {id: '', name: '-'} or {id: null, name: '-'}?

Solution

Update 2023-Jun

BIM360 issues API just released v2 API. Now it supports filtering assignedTo, assignedToType and displayId (in v1 called identifier). See here for the announcement: https://aps.autodesk.com/blog/bim-360-issues-version-2-api-released-1

Find the unassigned issues

curl --location --request GET 'https://developer.api.autodesk.com/issues/v2/containers/:issueContainerId/issues?filter[assignedTo]=null&filter[assignedToType]=null' \
--header 'Authorization: Bearer '

Find an issue by its displayId (in v1 called identifier)

curl --location --request GET 'https://developer.api.autodesk.com/issues/v2/containers/:issueContainerId/issues?filter[displayId]=14' \
--header 'Authorization: Bearer '

=========

We can specify null values to both assigned_to and assigned_to_type to remove the user from the issue and make it be unspecified.

curl --location --request PATCH 'https://developer.api.autodesk.com/issues/v1/containers/:issueContainerId/quality-issues/:issueId' \
--header 'Authorization: Bearer ' \
--header 'Content-Type: application/vnd.api+json' \
--data-raw '{
    "data": {
        "type": "quality_issues",
        "id": "{{issueId}}",
        "attributes": {
            "assigned_to": null,
            "assigned_to_type": null
        }
    }
}'
