[V2] Array Object Support in ModuleTwin #593

Closed matsujirushi closed 6 years ago

matsujirushi commented 6 years ago

Hi, When I set array object to module twin's desired properties, got below message:

Failed To Set Modules
BadRequest:{
 "Message": "ErrorCode:ArgumentInvalid;Provided json is not a valid 'tags' or 'properties' object: arrays are not supported."

I want to set leaf-device id's to module using module twin. So, do you have plan to implement that feature?

Hi Matsujirushi,

Yes, currently arrays are not supported in twin desired properties, as explained here - https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-device-twins#tags-and-properties-format. Currently there is no plan to add support for arrays.

Thanks, Varun

What is the rationale for the various limitations like no arrays? This ends up being very limiting because you can't properly represent a device as a twin properly.

Hello @v-tbert

You may want to provide feedback to the IoT Hub Team.

Specific use cases always help our team determine the need and priority of IoTHub features.

Please submit your vote on UserVoice. It would be great if you could also leave a comment on the exact content you'd like to put into the array.
