Google Search Console 4xx issue

Google Search Console just reported a “Blocked due to other 4xx issue” issue. I tracked down the link and found it in the source code on all pages of our website by this plugin.

wp-admin/admin-ajax.php?action=rest-nonce

<script type='text/javascript' id='dnd-upload-cf7-js-extra'>
/* <![CDATA[ */
var dnd_cf7_uploader = {"ajax_url":"https:\/\/www.domain.com\/wp-admin\/admin-ajax.php","nonce":"3fda55d77d","drag_n_drop_upload":{"text":"Drag & Drop","or_separator":"or","browse":"Browse Files","server_max_error":"The uploaded file exceeds the maximum upload size of your server.","large_file":"Uploaded file is too large","invalid_type":"Uploaded file is not allowed for file type"},"parallel_uploads":"2","max_total_size":"10MB","chunks":"","chunk_size":"10000","err_message":{"maxNumFiles":"You have reached the maximum number of files ( Only %s files allowed )","maxTotalSize":"The total file(s) size exceeding the max size limit of %s.","maxUploadLimit":"Note : Some of the files could not be uploaded ( Only %s files allowed )"},"heading_tag":"div","disable_btn_submission":"","preview_layout":"default","image_preview":"1","dnd_text_counter":"of","delete_text":"Deleting...","remove_text":"Remove","delete_files_on_failed":"1"};
/* ]]> */
</script>

How can this be fixed so that these errors aren’t reported by Google?

Thanks
