Service output infotable binding to navigation function leads to errors

[cjjaeckson]

Hello everyone,

My goal is to open pop-ups of different sizes in an SVG plan when clicking on different elements. For this I have built a service which calculates the required parameters for a navigation. Additionally I open different mashups in the navigation with different mashup parameters. In order to be able to bind them all in the navigation function, I have generated a dummy mashup with all existing mashup parameters (see images).

This works wonderfully in practice. However, in the background I am bombarded with error messages in the application log.
These are as follows:

Unable to dispatch [ uri = /Things/PersistentSessionfd8e1b3e-6e94-4cad-8e77-523fc0aa8f90/Services/AddDynamicRemoteSubscription/]: Unable to Invoke Service AddDynamicRemoteSubscription on PersistentSessionfd8e1b3e-6e94-4cad-8e77-523fc0aa8f90 : Validation Failure: Attempting A Dynamic Subscription To An Invalid Property [thingName] on [Lageplan_SVGVerwaltung]

error executing APIRequest Message: Validation Failure: Attempting A Dynamic Subscription To An Invalid Property [thingName] on [Lageplan_SVGVerwaltung], sending ERROR ResponseMessage to caller!

I suspect that the “AddDynamicRemoteSubscription” service always requires persistent values. Since the service only has values at the output during execution (this is just an assumption), this probably leads to problems.
Maybe someone has an idea to solve the problem? I am currently still working on version 9.3.7. Maybe this problem has already been fixed in the following versions?

Many thanks for your help!

Hi @cjjaeckson,

Please check out this article and check if any invalid property binding is configured in the Mashup.

Hi Tony,

thanks for your help. I search and search and cannot find a property that could cause the problem described.
Is there any way to get more information about the affected mashup or possibly even the faulty property itself?
The function “Automatically update values when able ” has always caused problems for non-administrators in our system. I have set all permissions according to this article. Unfortunately, it still does not work. After many hours of trial and error, I have already given up and am now working with an autorefresh, which is of course not the best solution. So if you have any suggestions, feel welcome to share.

Hi @cjjaeckson,

Can you check if entity Lageplan_SVGVerwaltung has a property called thingName? (which is mentioned in the error log) Is this property configured somewhere in the mashup?

If you cannot find the exact binding that caused this issue, maybe try removing the entity Lageplan_SVGVerwaltung from Data panel, re-add this thing and re-configure the related bindings from scratch?

Best,

Hi @cjjaeckson

Has there been any update on this issue? Were you able to find the affected binding?

Best,
