Describe the bug

It looks like the idempotency key is keeping a function cached, even when it's content is updated / rebuilt.

Only tested in dev.

Reproduction repo

not available

To reproduce

1. execute function (with idempotency key)
2. log run id
3. modify function
4. execute again (with idempotency key)
5. no new run (id remains the same)
