"trying to access contract instance key outside of the correct footprint"

[formal depot]

This happens when i require_auth on a contract from a different contract.

Can someone enlighten me about this error, what it means and how i can circumvent it?

Happens here: https://github.com/deep-ink-ventures/multiclique-protocol/blob/main/contracts/policies/elio-dao/src/lib.rs#L128 for me.

I'm at risk of stating the obvious here, but you're accessing contract instance key that is not in your footprint. the error should also have the address of the contract you're accessing
