Incorrectly formatted JSON

The plugin injects a JSON object in the page head that can be an incorrectly formatted JSON object if the post content includes the ” character. To fix this I added a str_replace call on line 44 of /app/services/review-schema.php to replace all occurrences of the ” character with \”.

$schema_reviews = '{
                "@context": "https://schema.org",
                "@type": "Product",
                "aggregateRating": {
                    "@type": "AggregateRating",
                    "ratingValue": "' . $get_overall_ratings_score . '",
                    "reviewCount": "' . $post->comment_count . '"
                },
                "description": "' . str_replace('"', '\"', $post->post_content) . '",
                "name": "' . $post->post_title . '",
                "image": "' . $args['featured_image_url'] . '"
                }';
