After adding the getproperties, don't show the getproperties properties
Yan He, are you on 7.2.0 by any chance? We had a known issue where services for a Thing with space(s) in its name does not render correctly on the Mashup builder, and has been corrected since.
Can you try upgrading to our newer 7.2.x release and retry? If you can't upgrade at the moment, you would need to use a Thing without spaces in its name as a workaround.
So how do I update to 7.2.0 version?
My version is 7.2.1
Hi Yan, you can check the upgrade guide at PTC Software Documentation for upgrading to ThingWorx 7.2
