Bug introduced by
The property offerClasses does not seem to exist. Did you mean offerClass?

An attempt at access to an undefined property has been detected. This may either be a typographical error or the property has been renamed but there are still references to its old name.

If you really want to allow access to undefined properties, you can define magic methods to allow access. See the php core documentation on Overloading.

Bug Best Practice introduced by
The expression $this->deliveryOptionClass of type null|string is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

In PHP, under loose comparison (like ==, or !=, or switch conditions), values of different types might be equal.

For string values, the empty string '' is a special case, in particular the following results might be unexpected:

''   == false // true
''   == null  // true
'ab' == false // false
'ab' == null  // false

// It is often better to use strict comparison
'' === false // false
'' === null  // false

Bug introduced by
It seems like $this->onValidationError can also be of type callable; however, pastuhov\ymlcatalog\models\BaseModel::loadModel() does only seem to accept null, maybe add an additional type check?

If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check:

/**
 * @return array|string
 */
function returnsDifferentValues($x) {
    if ($x) {
        return 'foo';
    }

    return array();
}

$x = returnsDifferentValues($y);
if (is_array($x)) {
    // $x is an array.
}

If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
