Trying to use Watson Document Conversion service from Node-Red with following payload setup and to feed into 'Convert' node, it always returns "Error: Lost connect to server". I'd think the setup is right per the document, but hardly find a way to make it works.

msg = {  
   payload:'http://www.nbcnews.com/tech/tech-news/got-parking-ticket-yup-there-s-app-n602566',
   normalized_html:{  
      "exclude_tags_completely":["script", "sup"],
      "exclude_tags_keep_content":["font", "em", "span"],
      "keep_content":{"xpaths":["//body/div[@id='content']"]},
      "exclude_content":{"xpaths":["//*[@id='footer']","//*[@id='navigation']"]},
      "keep_tag_attributes":["*"]
   }
}

Could someone provides help/advise for this? Thank you so much in advance!

Here is information from the command "cf logs":

Problem was indeed with the node and not with your code. It has been fixed and will be soon published to NPM, make sure that you restart Node-RED in order to get the last version of the Watson nodes.

Reference: https://github.com/watson-developer-cloud/node-red-node-watson/pull/164

Edit: Released in 0.4.8

This is most likely a problem with a http proxy, make sure you access the site via HTTPS

EDIT:

This looks like a problem in the document conversion node, you should raise a issue on their github page (github.com/watson-developer-cloud/node-red-node-watson) and include the log output.

  • After via https, same problem. Do you have a sample code which working for you to share? – nyker Jul 14 '16 at 01:13
  • To be clear I mean access Node-RED via. If this still fails then you will need to update your question with the Node-RED logs (`cf logs `) so we can see what is causing it to crash – hardillb Jul 15 '16 at 09:53
  • Great, here is logs, it seems the call crashing the server itself and make it to restart afterward. Please reference orginal question and i modified it to add logs when issue happened. – nyker Jul 15 '16 at 18:09
