FjordPoints contract doesn't set the staking contract address in the constructor.
In FjordPoints constructor should set the staking address as if not set it will be 0 address and all onlyStaking functions will revert. The staking address can be set by an admin but from comment it is expected to be already set and it can cause confusion and invalid transactions.
Not setting the staking contract will make all onlyStaking functions revert.
