Recently I faced a problem where my watch node was not responding.
As I was trying out zero touch node package creation, I had a few dlls referenced into dynamo’s app space.
As such i referenced 1 file which caused my watch node to not show any values.
So if anyone faces the same problem where the watch node is not responding, check if you have vmdatabridge.dll referenced, remember to change the ‘copy to local’ as never.
