Windows Server 2012
I have created a custom property of type Dataset with the following expression binding:
toDataSet(runScript("system.tag.browseTags(parentPath='Horizon OPC-UA Server/DeviceSet')"))
The expression appears to work fine because I get the exact results I was looking for.
I can save the project fine before adding this custom property, but I cannot save the project after I add the property.
I get this error below regarding a serialization error.
Any ideas what is causing this are appreciated.
