Fatal error on v1.0.3

[Karmalakas]

Fresh Grav 1.7.5 and up + Admin 1.10.5 and up
With Flex Objects 1.0.2 all is fine, but with 1.0.3 navigating to /admin/flex-objects ends up with error

Makes impossible to use FO on Admin Panel

I can confirm this error.

Adding this block in 1414 fixed it for me:

if (!$object) {
    return $this->object ?: null;
}
