Hi,I'm going to write an expansion package to get some data, but in ThingWorx I made the following mistake:
[context: com.thingworx.webservices.context.HttpExecutionContext@4f87ac83][message: Unable to Invoke Service ReceiverStringMessage on TestHttpThing : org.jboss.netty.handler.codec.http.HttpRequest.setHeader(Ljava/lang/String;Ljava/lang/Object;)V],
