I added this snippet of code in `fetch_channel`:
```
  yt_namespace = {"yt" => "http://www.youtube.com/xml/schemas/2015"}

  LOGGER.trace("fetch_channel: #{ucid} : Extracting videos from channel RSS feed")
  rss.xpath_nodes("//feed/entry").each do |entry|
    LOGGER.trace("START SCANNING ENTRY")

    LOGGER.trace("CHILDREN: #{entry.children}")
    children = entry.children
    children.each do |child|
      LOGGER.trace("CHILD: #{child.name}")
    end

    LOGGER.trace("NAMESPACES: #{entry.namespaces}")
    x = entry.xpath_node("author", yt_namespace).not_nil!.content
    LOGGER.trace("_____author: #{x}")

    x = entry.xpath_node("videoid", yt_namespace).not_nil!.content
    LOGGER.trace("_____videoid: #{x}")
  end
