Unable to push CSDK properties to ThingWorx 10.0.0

Hi,

I just installed ThingWorx 10.0.0 and created a service that will create

• User
• ApplicationKey for this User
• Organization with a Top Organizational Unit with the User as a Member

After this, the service create a new RemoteThing and sets visibility to the Organization and adds Runtime Permissions (property read/write, service invoke, event invoke/subscribe) and Design Time Permissions (Read).

With the ApplicationKey and thing name I can now connect a CSDK application.

The application has three properties and on changing the status of the "isConnected" property, the Platform will run a service that will create these remote properties on the RemoteThing.

However, when running the CSDK I can see that the properties are connected but they fail to synchronise with the following error in the CSDK:

[ERROR] 2025-08-20 10:58:30,206: twSubscribedPropsMgr_PushPropertyInfoList: Error pushing properties for ON1111-2. Error: 1111.
[ERROR] 2025-08-20 10:58:30,206: twSubscribedPropsMgr_PushProperties: error pushing or persisting property list, code: 1111

This continues throughout any restart of the CSDK (where properties are no longer touched on the RemoteThing). Only when restarting ThingWorx, the properties will synchronise.

Why would this be blocked, but starts working after a ThingWorx restart?

There seems to be some kind of permission issue, because everything works just fine with an Administrator-ApplicationKey.

Thanks for your help,

Michael
