I need to fetch the user assigned to the project using BIM360 Docs API, I have used the API provided. But it gives the internal error and there is not an error code either. I have used API from https://forge.autodesk.com/en/docs/bim360/v1/reference/http/admin-v1-projects-projectId-users-GET/
API: https://developer.api.autodesk.com/bim360/admin/v1/projects/{{ProjectId}}/users
Error: Internal server error and no error code
this is a known issue recently that you will need to specify region in the header. e.g. if your BIM 360 account is EMEA, then set the header when call GET: Project Users. If US, then US.
curl --location --request GET
'https://developer.api.autodesk.com/bim360/admin/v1/projects/:projectid/users' \
--header 'Region: EMEA' \
--header 'Authorization: Bearer ....'
Please let us know if it can work at your side
