Nullify Empty Fields for ACF is a WordPress plugin designed to enhance the functionality of the Advanced Custom Fields (ACF) plugin. This utility tool specifically addresses the issue of empty field values being set to 'false' rather than 'null', which can lead to GraphQL errors when integrating with GatsbyJS.

This plugin is free to use and serves as a valuable tool for WordPress developers utilizing ACF and GatsbyJS together. It streamlines the process of managing custom fields, ensuring that empty values do not disrupt the data flow within a GatsbyJS application. With simple integration, this plugin is a must-have for those looking to optimize their WordPress setup for modern web development.
