When I have the field active in the Gutenberg editor I get the following error when attempting to update the page/post: “Updating failed. The response is not a valid JSON response.” As soon as I deactivate the plugin or field it begins working again. I’m not sure if a new WordPress update or similar is causing this, but only last week everything was working fine.
