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.
