My block seems to work correctly, unfortunately none of my metadata gets saved after saving the article.

You can find source code for my block in this repository. It simply adds a toggle to set a meta value to false or true.

While the value to my attribute seems to change after calling:

setAttributes( { featured: value } );

If I save my post and check the rest api, the value actually won’t have changed.

I have absolutely no clue why this isn’t working. Is there anything wrong with the code?
