By the way, this happened on Linux
Are you trying to modify an extract that is on a network share? If so, it might be worth trying to modify a local copy on your machine. This error has been seen before when multiple users are connecting to the same extract in a shared location.
I am using the python API to create an extract on an ubuntu image on AWS. No one has access to this but me.The issue seems to be the inability to load one of the shared libraries but I can't figure out how to fix this.
