Closes #4452.
When
SetError
is called in a command,res.Next()
returns the error "received command error" makes the error set by the command available by callingres.Error()
. To make handling these errors easier, the functionscmds.HandleError
was added. Unfortunately we forgot to use it in the get command.The add command did the right thing, but manually instead of calling HandleError. I made it call that function instead.
