invokehttp NIFI not translating URL as I expect

New Contributor

I am trying to get Httpinvoke to retreive a url. When I paste in the URL it retreives it. When I read it form a file, extract the text, put the url into an attribut and reference this attribute I get the folowing error: No value set no protocol: No value set
