Hi Kun,

I’ve fixed the issue and released a new version of LiftOn (v1.0.5): https://github.com/Kuanhao-Chao/LiftOn/releases/tag/v1.0.5
The error occurred because the IDs for each feature in GTF files are different.
For instance, it’s gene_id for genes, transcript_id for transcripts, and so on, whereas in GFF files, it's always ID.
It wasn't properly handled, which caused errors when extracting features from the gffutils database.

Thanks for reporting this error.
Best,
Kuan-Hao
