KeyError on spidesc parser

[0xfede7c8]

With the attached SPI flash dump (after extracting):

Supermicro_bios_firmware_unpacked_00a3a39e78b51d6ecd83bb789431e43d9175a5a1_X11DPS8.A03.zip

python3 chipsec_util.py --no_driver --skip_config spidesc Supermicro_bios_firmware_unpacked_00a3a39e78b51d6ecd83bb789431e43d9175a5a1_X11DPS8.A03

I get:
