When inspecting the wsk trigger update <trigger-name> command it was shown that you can specify a -p to update parameters.

When I tried to do this it failed with a response mentioning
""error": "no updatable parameters were specified""

Upon inspecting the command with a -v it is revealed that when the update command calls a POST to the Feed it is getting back a 502 error. Something about this 502 error is causing it to not update the Trigger.
