I can see you mentioned ACC Sheets API, and its API call was successful. https://developer.api.autodesk.com/construction/sheets/v1/projects/{project_id}/sheets
If so, you cannot use Data Management API to get the sheet versions, as this sheet is not managed by the Autodesk Docs. It's under the ACC Build's Sheets service.
According to our product help, please check the version sets instead and then get sheets by versionSetId.
