Hi all!
I've successfully written a block with Metabox and all works fine and as expected for months. Today, i've stumbled over a potential conflict with Beaver Builder.
If Beaver Builder is installed and i hit the "Launch Beaver Builder" button in the Gutenberg Editor, a JavaScript error occurs "Uncaught TypeError: Cannot read properties of undefined (reading 'then')" in react-dom.min.js and obviously the page stucks at that point and the Beaver Builder page builder doesn't load.
Not sure who is the culprit, however, if i deactivate my Gutenberg Block, the issue is gone.
On my test site i run only the free version of Beaver Builder and my Gutenberg Block written with metabox.io.
It should be simple to replicate. Can you please help?
