Or maybe it’s an entirely different problem (e.g. maybe this code shouldn’t be run when loading the block editor in the first place). * Any help debugging the issue is appreciated. 🙇 Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Support [Jignesh](https://wordpress.org/support/users/jigneshmpatel/) * (@jigneshmpatel) * [8 months, 1 week ago](https://wordpress.org/support/topic/error-throw-when-opening-block-editor/#post-18658594) * Hello [@butchler](https://wordpress.org/support/users/butchler/) * Thank you for providing detailed information about the issue.
