i have tried quite few things already, , continue so. if of had similar problem please let me know. little illiterate when comes couch error log. think understand gist of it, maybe not if me make little more sense out of log. thank you!

i lucky debugged pretty fast. following direction of https://wiki.apache.org/couchdb/http_document_api#inline_attachments realised made silly mistake. forgot name attached file itself. revise line

  var doc = { "_id":items[i].children[1].textcontent, "_attachments": {"content_type":"text\/plain","data":window.btoa(items[i].outerhtml)}} 

into

    var doc = {"_id":items[0].children[1].textcontent, "_attachments": {"items_metadata":{"content_type":"text\/plain","data":window.btoa(items[0].outerhtml)}}}
