Error Executing Event Handler 'ForwardEvent'

[AliBenBelgacem]

Hello

I have a mashup with a led widget. I use getproperties to get the value and i am activating the auto update values from mashup

I have a weird behavior :

When i change the value manualy from the thing the property is updated automaticaly on the mashup (no problem)

When the value is changed from subscription function , the value is changed in the thing but  the led value still not changing and i have this error on the log monitor :

Error Executing Event Handler 'ForwardEvent' for event Type.Thing:Entity.MyThing:Event.DataChange

I get the value only when i refrech manualy the page.

the auto refresh widget does not exist so i have no other alternative.

I search in all the topics in the community but none is a solution : 1 here  and 2 here 

My thingworx version is :9.1

My code work perfectly on 9.3 version

Any help is welcome.

Thank you.

Hi @AliBenBelgacem,

I can't comment about why this happens, but can you please add which ThingWorx versions you refer to? You mentioned only the major and minor versions in the original post, but it is not enough to detect where the change might have happened, since we have 15 "9.1" releases and 6 "9.3" releases.

I suspect a bug that was fixed, but that's the most I can say from what you mentioned.

Weirdly, it was a licence issue. we re installed the licence and it's esolved

Hi @AliBenBelgacem 

This isn't indicative of a licensing issue.  Did you perhaps change permissions?

Regards.
