Just got this error on a new content type I created. The solution was to make the Body field optional.
i installed gutenberg on my preproduction server. Ubuntu 20.04 with varnish and nginx. On a drupal 9.1.0. I installed three versions, 1.11, 2.x-dev and 2.0-beta2. The problem is the same.
Cannot save document or preview it. I have in the dev console, the following message: An invalid form control with name = 'body [0] [value]' is not focusable.
(anonymous) @ gutenberg.js? qm3hu5: 275
dispatch @ jquery.min.js? v = 3.5.1: 2
v.handle @ jquery.min.js? v = 3.5.1: 2
Locally everything is going well.
Closed: cannot reproduce

It's likely this issue predates Contrib.social: some issue and comment data are missing.
