Hi @tbenst
There’s been no active development going on in this repository for some time.
Please check out https://github.com/RomanArzumanyan/VALI which is VPF spin off. It’s actively developed and maintained. It also has compatible API and module naming.
You can simply duplicate your issue there if it reproduces on latest version.
