schedule command isn't working or i'm misunderstanding something

i'm trying to make a function schedule another function in 1 tick, but it's not working
schedule function magic_items:endless_stew_2 1t replace
the advancement i'm using to activate a function works, and the function it's referencing works, but neither the function this one is in nor does manually using the schedule command works
is there something wrong with how i'm using the schedule command?
