What causes the error: "Invalid value format" and how to fix it?

Question

Yii

Hello everybody! When submitting the form, in the field with the date and time I get the error "Invalid value format".
Date field in the submit form:

<?= $form->field($model, 'date_filing')->widget(DateTimePicker::className(),[
    'name' => 'dp_2',
    'type' => DateTimePicker::TYPE_COMPONENT_PREPEND,
    'pluginOptions' => [
        'format' => 'd M yyyy H:i',
        'autoclose'=>true,
    ]
]); ?>

In the validation rules I have:

[['date_filing'], 'datetime', 'format' => 'php:d m Y H:i'],

Can the error occur due to the difference between the date / time formats in the widget and the validation rules?
