It seems that the current grammar is not compatible with Lark 1.0 (https://github.com/lark-parser/lark/releases/tag/1.0.0)

Now the version is fixed to lark<1.0

Goal is to stay up to date with lates lark

Lark is several versions beyond 1.0 now. Any word on when this might get updated?

This affect pip installation for other packages and dependencies - as per: mappyfile 1.0.1 requires lark>=1.1.5, but you have lark 0.12.0 which is incompatible.
