Are we sure this is an o1js bug and not related to the how it's used in the project mentioned on Discord?

no!

The Pool contract is deployed manually with the vk in the Factory contract. The Pool contract is not initialized automatically, and the init method needs to be called explicitly. The error disappears once it is initialized.
