    See https://github.com/kubernetes/kubernetes/issues/89899 - which explains there's currently no way to indicate end of input over a websocket, so you may not get an exit code when using stdIn.

    Parameters:
    
    code - the exit code, -1 will be used if the code cannot be determined
    
    status - may be null if no valid status was received
