I hope you don't find it nonsensical, though, I understood it just fine.
And checking ghits for plain forms shows:
"学校に行く" - 3,680,000
"学校へ行く" - 444,000
so I think the other way is actually the variant!
BTW, I feel like "学校に行く" - where に means "for/into" - has a sense of "going to school to go to class", but "学校へ行く" - where へ means "towards" - has a sense of "going to the school building as a physical place".
