Customer Issues Solved
Issue Description ID
Update of a Device in AppIoT 2.0 keeps the previous Device Identifier. Improved Device update request. Removed the requirement to include unchangeable properties when using API endpoint PUT /api/v3/devices/{id}. DDM-14380
DDM-87318
Updating a DataCollector without passing TagIds parameter result in an error. Improved validation. Swagger documentation correctly stated the property TagIds as optional but resulted in an error if left out. DDM-86616
API call GET /api/v3/measurements/{resourceId}/aggregation does not return data values. Improved Swagger description to clarify that both AggregationType and Resolution must be set when using API endpoint GET /api/v3/measurements/{resourceId}/aggregation. DDM-87178
DDM-87199
Faulty formatting in API documentation for release AppIoT_2018_35 (DDM Core). Fixed incorrect remark position in Swagger for API endpoint POST
/api/v3/resources/measurements.
DDM-87411
Error while attempting to delete Device. Improved rules to not store measurements of attached resources. The previous behaviour could lead to too large files, which could result in Devices that could not be deleted. DDM-87434
