How can the PUSHINT OP code cause a stack underflow error?

I wrote a program in Fift, which included the following code:


I receive the following error: "PUSHINT: stack underflow"

This doesn't make sense to me, since it's adding a positive number. How does it throw the stack underflow error?

PUSHINT is TVM-asm instruction and required for assembling the smart contract. Analogue from Fift is just writing number 1 or any other that you want.

Using TVM opcodes outside of smart contract is not possible.
