KeyError: 'L1_METADATA_FILE'

Hi guys,

I am getting this error from a couple of 2014 Landsat8 images.
I installed rio-toa using pip and github but nothing works.
Any advice?

Thanks in advance, JL

KeyError: 'L1_METADATA_FILE'

Start with the traceback in reflectance.py, especially calculate_landsat_reflectance, and inspect how _load_mtl parses the affected 2014 Landsat 8 metadata. Reproduce the error with the reported images and compare the parsed structure with the expected L1_METADATA_FILE entry. Done means identifying the cause and documenting or confirming the required next action.
