I've seen this error being reported before. LuckPerms does not officially support hybrid server software. However, your mohist build is 6 versions behind. Try updating it, and if that also fails, two people have reported switching to magma to work, so might be worth considering that.
i have updated my mohist 1.16.5 from #1061 to #1067. the problem are the same. sad that Magma doesn't support a higher minecraft version.
As they said, hybrid software is not supported due this problems. A lot of bugs are on way and can't really be solved.
I really suggest you split your servers on plugins - mods!
