In this branch, the function will implicitly return null which is incompatible with the type-hinted return string. Consider adding a return statement or allowing null as return value.

The method getFullName() does not exist on yii\web\IdentityInterface. It seems like you code against a sub-type of yii\web\IdentityInterface such as craft\elements\User.

It seems like Craft::parseEnv($settings->vanillaForumsClientID) can also be of type boolean. However, the property $vanillaForumsClientID is declared as type string. Maybe add an additional type check?
