Hello David, The .gfid directory is there but you cannot traverse (cd) in it - you need to specify just like in the example.I had some cases where the 'transprt endpoint is not connected' was received, but usually this is due to a gfid missing. About the meetings, one of the topics is discussing open bugs and issues reported in the mailing list. It will be nice to join the meeting and discuss that in audio, as there could be other devs willing to join the 'fight'. @Sankarshan, any idea how to enable debug on the python script ?
