Icepyx 'normalproj' errors

I have been running into issues when using icepyx to download ATL03 data.
I have copied an example of the code and corresponding error below, which appears with other Query options, such as region_a.order_vars.avail().

Any help would be greatly appreciated!

Code example:
region_a = ipx.Query('ATL03',[-54.42, 65.41, -49.10, 68.34],['2019-02-22','2019-02-28'], \ start_time='00:00:00', end_time='23:59:59')

region_a.show_custom_options(dictview=True)

Output Error:

Hello @jaha2600! Thanks for reaching out and bringing this to our attention. It looks like you’ve stumbled upon an error that arose after a change at NSIDC, which is how icepyx accesses the data. The error is logged on GitHub. Someone from NSIDC was working on this, so I’ll reach out and see if they’re ready to merge the fix. Once that happens, if you update your install of icepyx you should be all set.

Update: as of last week, this issue should be resolved in release 0.3.2 of icepyx (which is available via PyPI for pip install icepyx as well)
