Trouble Downloading PDF from API via Custom Connector

I am trying to create a custom connector that send to a custom API which converts and returns a PDF.  It works with Postman if I "Send and Download" the request, and almost works with the custom connector.  Testing it returns a 200 code but the file doesn't download.

 

When I Try it Out, in the swagger view, I get 2 responses although I expect only 1, the PDF.  The first response in Server Response and it appears to be the file, albeit a txt file instead of PDF.  The second response is called Responses and appears link with the swagger file , but only shows "Example Value... string".  I suspect that a specific tweak of the swagger file will get it to work as expected.  Any ideas?

 

Here is the swagger and Try it out results:

Hi @rarroyo1

I think you have a fair bit of work to do on your swagger document.

  • The consumes and produces value should be "application/json" and not blank or the mime type of the generated document.
  • The response schema should cover all the properties returned, with the document similar to:
  • "FileContent": {
    
              "format": "byte",
    
              "type": "string",
    
              "x-ms-visibility": "important",
    
              "x-ms-summary": "File Content",
    
              "description": "The processed document."
    
            }
