Fixes #1827
In the current implementation, if a
Pipelineis created with an error due to the connection being busy/closed, callingSyncon thatPipelinewill result in a nil dereference panic. An example of where this behaviour can be seen is here.This PR adds a check to the start of the
Syncmethod to return an error if thePipelineis "closed".
