Validation error in custom tag

Hi, i found a problem while sending form with custom tags.

The form gave me error 500 generated by wp-json/contact-form-7/v1/contact-forms/3497/feedback

So i activated wp_debug and found this:

[28-Feb-2023 14:05:19 UTC] PHP Fatal error:  Uncaught Error: Call to a member function get_invalid_fields() on null in /home/ima/public_html/wp-content/plugins/contact-form-7/includes/submission.php:645

#7 /home/ima/public_html/wp-includes/rest-ap in /home/ima/public_html/wp-content/plugins/contact-form-7/includes/submission.php on line 645

So i checked my from and i use three custom tag, if i remove these custom tags the form works again.

I use the tag validation filter like this:

add_filter( 'wpcf7_validate_ima_acceptance1*', 'wpcf7_checkbox_validation_filter', 20, 2 );

and i found out that if i remove this validation the form works again, so the problem is in this code.

Can you help me understand where the problem is?

Thanks!
