Hi @marcusjwilson
Thanks for the debug info.
The line you are referencing is this:
// Hack for CPT without a content editor
try
{
wp.media.view.settings.post.id = acf.post_id;
}
catch(e)
{
// one of the objects was 'undefined'...
}
Which to me is safely wrapped in a try / catch block. I don’t understand why this would cause an issue, but it clearly is…
