Hello team Icepyx,

I am running into the same problem with `reader.load()`. When I try to load the data use reader.load(), this returns a KeyError: ‘orbit\_info’. When running region\_a.order\_granules(), I also noticed that four granules are missing some data (e.g. ‘Granule 229005537 contained no data within the spatial and/or temporal subset constraints to be processed’).

My intention is to use the ICESat2 ATL06 v05 product to look at elevation change/anomalies over a small region of the East Antarctic Ice Sheet. I want to be able to visualise the data, and then potentially later convert to a geopandas dataframe to work further with it in GIS.

Have you got any suggestions for working around this error?

My download query and code for loading the data is:

```auto
short_name = 'ATL06'
spatial_extent = "filepath to polygon shapefile"
date_range = ['2020-01-01','2020-02-28']
region_a = ipx.Query(short_name, spatial_extent, date_range)
region_a.earthdata_login(earthdata_uid, email)
region_a.order_vars.append(defaults=True,var_list=['latitude','longitude','h_li']) 
region_a.subsetparams(Coverage=region_a.order_vars.wanted)
region_a.order_granules(verbose=True, subset=True, email=True)
region_a.download_granules(path)

path_root = 'filepath to download location'
pattern = "processed_ATL{product:2}_{datetime:%Y%m%d%H%M%S}_{rgt:4}{cycle:2}{orbitsegment:2}_{version:3}_{revision:2}.h5"
reader = ipx.Read(data_source=path_root, product="ATL06", filename_pattern=pattern) 
reader.vars.append(var_list=['h_li', 'latitude', 'longitude'])
ds = reader.load()
ds

```
