title: Enter a valid URI error in Azure Logic Apps
body: <p>I am currently trying out Azure Logic Apps and am now trying to create 
  a first simple flow that acquires data from an external REST API. </p>
  
  <p>I'm using FRED, a hosted Node-Red instance, to create an REST API end-point.
  In FRED you use <a href="https://x_y.fred.sensetecnic.com/api/hello" rel="nofollow noreferrer">https://x_y.fred.sensetecnic.com/api/hello</a> to access my mock API (where x_y is my user name).</p>
  
  <p>Accessing "<a href="https://x_y.fred.sensetecnic.com/api/hello" rel="nofollow noreferrer">https://x_y.fred.sensetecnic.com/api/hello</a>" in a browser returns the intended data as specified in the Node-Red flow. Same thing goes when accessing
  "<a href="https://x_y.fred.sensetecnic.com/api/hello" rel="nofollow noreferrer">https://x_y.fred.sensetecnic.com/api/hello</a>" using GET in Postman (then adding two required Headers, required by FRED).</p>
  
  <p>The strange thing is that in my Azure Logic App, I am not able to even save the flow with my URI stated as "<a href="https://x_y.fred.sensetecnic.com/api/hello" rel="nofollow noreferrer">https://x_y.fred.sensetecnic.com/api/hello</a>". It states "Enter a valid URI". I enter the headers as was required.</p>
  
  <p>So I can get to the REST API directly from a browser or using Postman, but are not able to access it from within an Azure Logic App.</p>
