ValueError: NULL dataset after download and process

[cwadding]

I am running landsat to download and then process some bands. Everything seems to work fine but I am getting the error ValueError NULL dataset in the final steps after calculating the cloud/snow coverage.

ValueError: NULL dataset

I am running through the docker container on windows 7. I am not sure what the error means or why I am getting it.
