SynchronizeModelState service failed on edge thing

javed_a — Tue, 07 Oct 2025 05:51:10 GMT

Hello All,

I am using GetProperties service from Dynamic ThingShpe, I have enabled automatic value update.

The properties which are being bind are set via service as it is calculated field (Not logged but persist). Thingworx version : 9.7

On page load I got warning in application log as below:

ApplicationLog

On Mashup log, below info shown:
MashupRuntimeLog

Any idea why I am getting this warning in application log, and how to avoid this.

This is expected: the AlwaysOn JS client in Mashup does not yet implement the SynchronizeModelState service. The platform will fall back to the legacy service if this one fails.

Thank you for your response.

How ever I am not using remote properties, the value are being set by a service on a refresh logic.

And the source properties are being set via subscription as data coming from MQTT.

PTC says it can be ignored but any further insight in it to avoid the warning.

That service is invoked after every bind (irrespective if you have remote properties). I will report to R&D if it hasn't been done.

@smainente Thank you for information.

Agree with your point but too many warning in application log does not looks good. Did R&D team have any work around it.

To add more information, I am using getproperties along with collection widget.

Hi @javed_a

As documented in https://www.ptc.com/en/support/article/CS423838, this has been reported to R&D as an enhancement request and is currently under internal discussion.

In the meantime, have you tried adjusting the ApplicationLog level in the composer to suppress these warning messages?

Thank you for the update, we will ignore this warning for now. We are not suppressing as there might be other relevant warning, or is there specific way to suppress specifically this type of warning?

Hi @javed_a

I'm not aware of any method to suppress a specific warning—at least not to my knowledge.

I guess you could try customizing the logger through the Logback configuration file. However, as you mentioned, this approach may also filter out other relevant warnings.
