Hi  @VladimirRosu_116627,

I installed the extension in ThingWorx (version- 9.3.1) which is available under Build section from the github link you shared (in topic) and tried to execute the services -

GetLastMessages, SendMessage with the following configuration:

but the result is, ErrorCode(6bbd1442-4b7b-4b88-ab6b-125feb8812e2), Cause(null), Reason(Access was attempted on a null reference variable.), Possible Resolutions(Remove the reference to the null variable within your extension code. 
Note: ActiveMQ is up and running

Can I get any help to resolve this?

As for any other open source third party extension, you would need to effectively debug it on your end, especially since it's an extension that it is very old, as I mentioned in the other post, not supported by anyone.

 

Assuming you are familiar with Extension development, if I would be to guess, most certainly you need to rebuild it with the ThingWorx Extension SDK 9.x (and when doing that, you'll be forced to modify the lifecycle method signatures to  include the new ContextType parameter, otherwise it won't compile with the new SDK).

 

In case it's needed, you can debug it by following the steps in this article (you will need a local development environment, as passing those Java args is not doable in a PTC Cloud hosted environment due to security reasons).

Thanks for the guidance. I will debug it and build with the latest SDK.
