Doh! Thanks!

Everything working now. Final solution:

• Uninstall the WPDM Gutenberg editor plugin
• Add these 2 lines to .htaccess (in the root of the WP public_html folder)below RewriteEngine On

RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]

Some progress here. It appears that the Gutenberg addon for WPDM has a conflict with the REST API Addon. For reasons unknown to me, it registers its own endpoints in the same namespace as REST API like so:

register_rest_route( 'wpdm/v1', '/search-package', array(
            'methods' ► 'GET',
            'callback' ► array($this, 'searchPackages'),
        ) );

Now unfortunately, the routes are found, but I am unauthorized (401).

Also, fwiw, I have uninstalled and reinstalled both the REST API addon and the Download Manager plugin itself. Neither resulted in any change.
