TypeError: c is null in hesh.min.js

Hi,

I’m getting a js console error in my Admin pages which seems to be coming from /wp-content/plugins/html-editor-syntax-highlighter/lib/hesh.min.js

line 1 column 2341, to be exact.

TypeError: c is null

…[t],i=n[2]?’data-prompt=”‘+n[2]+'”‘:””c.insertAdjacentHTML(“afterbegin”,'<input…

Console indicates it is just before insertAdjacentHTML

I’m not sure if this is breaking anything, but I thought it might help if I passed along this error message.

Note: This only occurs when editing custom post types. Custom post type editing page is made using ACF (Advanced Custom Fields) plugin, where the “wysiwyg” editor field-type does not have “visual” and “text” tabs; basically only “visual”.
