I am trying to: Add a link to a bullet point via the wp visual editor in inside a bullet list

Link to a page where the issue can be seen:
hidden link but only in the wp admin

I expected to see: no jquery conflict issue.

Instead, I got:
Uncaught TypeError: Cannot read property 'split' of undefined

issues seems to be here:
if ( linkNode ) {
$linkNode = editor.$( linkNode );
nodeClass = $linkNode.attr( 'class' ).split( ' ' );

maybe better to check if node exist before referencing it.
if ( linkNode ) {
$linkNode = editor.$( linkNode );
if( $linkNode.hasAttr( 'class' ){
nodeClass = $linkNode.attr( 'class' ).split( ' ' );
}

i am running most up to date toolset plugins and have tried switching to default theme and issue still persist.

Hi, I'd like to try to reproduce this problem locally but in my first few tests I wasn't able to see a JavaScript error. Can you tell me a bit more?
- Is this the main post editor area, or a WYSIWYG custom field?
- Are you editing a post or a Content Template, View, etc?
- Are you adding an external link or searching for an internal page link?
- Are you using the Classic editor or the Block editor?
- Can you attach a full screenshot so I can see everything that's going on?

Thanks!

I've attached a screenshot. It only happening when trying to add a link to a bullet list. It simply won't open so it happens before you are able to add ant type of link. It is in the default WYSIWYG editor. There is not view being used on this page. We're using the classic editor. I've tried default theme and same issue. I've also deactivate views and confirmed the the issue goes away.

It seems the spit is occurring because of an extra div tag that does not contain a class. If you remove the div or add a class it will work fine. Of course, removing the div is fine, but the plugin code is assuming that all users will know to add a class. Which assume a lot for people learning html and that are learning WordPress and proper html semantics.

Adding a conditional to your plugin to check if class exist would probably solve this use case.

if( $linkNode.hasAttr( 'class' ){
nodeClass = $linkNode.attr( 'class' ).split( ' ' );
}

Thanks for the extra information. I'm able to reproduce this issue on one of my local test sites but not on a site created from scratch. I'll need to put some additional time into this tomorrow and give you an update when I have some more information to share.

Okay I was able to figure out how to reproduce the issue consistently. In my local tests, it has to do with whether or not the Toolset Blocks plugin was ever active on the site. Until I activated Toolset Blocks, I could not reproduce the problem. Then once I had activated Blocks even just once, I could continue to reproduce the problem even after Blocks was deleted from the site. I'm asking my 2nd tier support team for some clarification on how to handle a problem introduced by a beta that continues to affect the site after the beta is uninstalled. I'll let you know what I find out.

Hi, just a quick update to let you know my 2nd tier support team has escalated this issue to our developers. I'll keep you up-to-date here and let you know when I have additional information to share.

Hi, I have been informed by my second tier support team that this issue should be resolved in the latest versions of Views and Blocks. Please be sure your site is updated to use the latest plugin versions, and let me know if the problem is not fully resolved. Thanks for your patience!
