Hi, 

Out of nowhere, I started getting an error message when saving the Mashup during development. 

The error message is 

Save failed: Unable to update mashup: property name projectName not found.

 

Thanks,

Hey, 

As of now, I have cleared the Tomcat cache and restarted Thingworx. The error disappeared. 

Thanks.
