I'm trying to use the ThingWorx OPC UA service but running into some problems. I can create an OPCUAEndpoint thing and connect the OPC UA server to ThingWorx, and in Composer I can see the OPC tags as remote properties under "Manage Bindings", but when I try to save the endpoint thing after adding a remote property I get the following error message in Composer:
"save failed, status: Internal Server Error message: JSONObject["baseType"] not found."
Any ideas why I can't save the remote properties?
Greg, is it for all property basetypes or specific ones?
Isn't this the error that appears when there are ghost entities?
Is there a remedy for this issue? I have the same problem.
Would a Thingworx or Tomcat restart work?
I did try restarting Thingworx (7.1) from the Tomcat Manager App in browser. I think that worked.
My problem had something to do with a service I wrote for adding a selected list of tags. I'm not for sure which part of it yet.
So a restart of Thingworx/Tomcat may do the trick to get rid of ghost entities.
