Version problem github actions documenter.jl build

i have a problem with building docs on gh-actions. locally no problems. I see this log on the runner:

   Resolving package versions...

 Flux [587475ba] log:

LandUse is my package. why does it cause problems for Flux? here is my Project.toml, where I removed the compat entry because i thought that’s the trouble maker.
