Actually, I’m not sure upgrading will solve the problem. It looks like this never got fixed (DM-15181 and DM-28880 are both listed as “To Do”).
DM-15181 suggests the issue might be caused by generating the skyMap on one machine and using it on another (e.g., MacOS vs Linux). If that’s the case here, you could work around the problem by sticking to a single machine.
