< mysterious train 91935> The `ConnectionResetError` suggests that the target closed its stdin stream prematurely possibly because it ran into an error and shut down Do you see any output related to the target ahead of these log lines And are you seeing this error consistently when running this pipeline or only occasionally I don t think the lost connection would be caused by v1 64 0 but in earlier versions you would have seen a different error message from a different code path It s also possible that behind the scenes the connection would also have been closed list before but would not have resulted in an error message at all I ll look into it some more but it ll be good to know if you re seeing this every time or just sometimes
