Hi,
my code:

<?php
                        $schema = array(
                            '@context' => "https://schema.org",
                            '@type' => "FAQPage",
                            'mainEntity' => array()
                        );
                        global $schema;
                        if (have_rows('pytania_i_odpowiedzi')) {
                            while (have_rows('pytania_i_odpowiedzi')) : the_row();
                                $questions = array(
                                    '@type' => 'Question',
                                    'name' => get_sub_field('pytanie'),
                                    'acceptedAnswer' => array(
                                        '@type' => "Answer",
                                        'text' => get_sub_field('odpowiedz')
                                    )
                                );
                                array_push($schema['mainEntity'], $questions);
                            endwhile;
                            function generate_faq_schema($schema)
                            {
                                global $schema;
                                echo '<script type="application/ld+json">' . json_encode($schema) . '</script>';
                            }

                            add_action('wp_footer', 'generate_faq_schema', 100);
                        }
                        ?>

I am getting an error:
array_push() expects parameter 1 to be array, null given

How to fix it?

I have a solution

global $schema;
                        $schema = array(
                            '@context' => "https://schema.org",
                            '@type' => "FAQPage",
                            'mainEntity' => array()
                        );
