403 Forbidden with gutenberg

In case anybody comes across this, I had the following in my apache config

<Directory "/home/*/Sites">
    AllowOverride All FileInfo AuthConfig Limit Indexes
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    Require method GET POST OPTIONS
</Directory>

The WP API was trying to use the method PUT. I also believe it sometimes uses the method DELETE.

Changing above code to this solved it for me:

<Directory "/home/*/Sites">
    AllowOverride All FileInfo AuthConfig Limit Indexes
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    Require method GET POST PUT DELETE OPTIONS
</Directory>
