Some view functions will not work under certain conditions

function getStrategyCR() public view returns (uint256) {
    return (getMarginValue() + getExposureBalance()) * WAD / getDebtBalance();
}

function exposurePositionWeight() public view returns (uint256) {
    return getExposureValue() * WAD / getCurrentPositionValue();
}

function collateralPositionWeight() public view returns (uint256) {
    return WAD - exposurePositionWeight();
}

function getStrategyLeverage() public view returns (uint256) {
    uint256 positionValue = getCurrentPositionValue();
    return positionValue * WAD / (positionValue - getDebtBalance());
}
