During the creation of the client app, where on submitting the thermostatModel.json, and the SpaceModel.json, I encounter an error which says:
Submitting models: ThermostatModel.json, SpaceModel.json...
Response 409: Service request failed.
Status: 409 (Conflict)

Hello @Nikunj Phutela ,

The initial Client APP worked perfectly with no issues from our side.

Could you please confirm if you are trying to achieve this for 33 Rooms and 33 Thermostats?

Hello @QuantumCache , the client app works perfectly when I run the demo, but does not work when I use anything other than the demo, like a custom client app, is there a specific reason for this?

Hello @Nikunj Phutela , Did you tried to run the app for the second time?

Have look at the section just above this Catch errors

I can repro the issue, the reason is running twice the same Model.

We can check the existing Models from Azure Digital Twin Explorer.

So must I create a new digital twin each time I make some modification in the digital twin?

I will check out the ADT Explorer, and try visualising my relationships from the given program, if any doubts persist, I will revert back to you
