It seems like you are loosely comparing $helper->getConfig('xhelp_defaultDept') of type mixed|null to 0; this is ambiguous as not only 0 == 0 is true, but null == 0 is true, too. Consider using a strict comparison ===.

It seems like $helper->getConfig('xhelp_defaultDept') can also be of type null; however, parameter $value of XoopsModules\Xhelp\Utility::setMeta() does only seem to accept string, maybe add an additional type check?
