Error: "Object reference not set to an instance of an object" on Linux with Docker

[pygospa]

When using it with docker (Docker version 20.10.12, build e91ed5707e) on Arch Linux (5.15.13-arch1-1), with both documented variants I'll get the above error, which according to my research is a common null pointer in C#. I also tried out different flags such as the -w (whole) to see if I need some additional settings, but everything leads to the same error. My guess is that something is going wrong with the device path, as the "Scan completed successfully" is really fast.

Here is the output:

./bdinfo /dev/sr0 /home/pygospa/report
Please wait while we scan the disc...

Then the directory that you scan is not the proper directory.
Had the same error. I was scanning: /SOME-MOVIE/BDMV
while I should have been scanning: /SOME-MOVIE
You shall scan the folder which at least includes these directories:

• BDMV
• CERTIFICATE

Please also make sure, read rights are given.
