Error: Call to a member function get() on null in Drupal\feeds_http_auth_fetcher\Feeds\Fetcher\HttpAuthFetcher->fetch() (line 43...)

I'm trying to use the module to import a json from a URL with an bearer token but I get this error:

Error: Call to a member function get() on null in Drupal\feeds_http_auth_fetcher\Feeds\Fetcher\HttpAuthFetcher->fetch() (line 43 of /var/www/html/web/modules/contrib/feeds_http_auth_fetcher/src/Feeds/Fetcher/HttpAuthFetcher.php)

The line in the module is:

        $destination = 'temporary://';
        if ($this->configFactory->get('feeds.settings')->get('feeds_temporary_dir')) {
            $destination = 'public://';
            // Remove all files by mask before imported files as not needed any more.
            array_map('unlink', glob($this->fileSystem->realpath($destination) . "/feeds_http_fetcher*"));
        }

Where can I configure "feeds_temporary_dir"?
