Error when running rootfs pipeline on rootfs tarball

[cco3]

This doesn't happen for me on all images, just some, so I don't know what the issue is. (I haven't really investigated the code here.)

'NoneType' object has no attribute 'merge'

Traceback:

@cco3 which version of the code are you running? A branch or the latest release?
For reference, we've been working on this issue in #132 (comment)

[cco3]

latest release (v21.5.12). This doesn't fail with all qcow2 images, just some.

@cco3 thanks. We already have implemented a fix for this one. I'll prepare a new release and let you now when its ready.

@cco3 the fix is now available in the latest release https://github.com/nexB/scancode.io/releases/tag/v21.6.10
