Web.Contents() doesn't support status code 308

I am trying to pull in data from predicthq.com.  I'm not connected with this group other than as a data consumer.

 

Their webservice has a 308 redirect.   From the docs I can see Web.Contents() has the required redirection logic for 300-307.

I've tried extending this function with a re-try request having no success - see below.   Python works as does Postman. 

 

Any workarounds for this?    Using Python I've checked the history of the response and I can verify the 308 and the redirection to the final location which happens to be, annoyingly, the same uri as in my original request.    

 

 

 

let req = () =>
    
    let
        
        uri = "https://api.predicthq.com",
        
        utiResponse = Web.Contents(uri, [RelativePath="/v1/events",
            
            Headers = [
                #"Authorization" = "Bearer privatekey",
                #"Accept" = "application/json"
    
            ],
            ManualStatusHandling={308}
        ]),


        finalResponse = Web.Contents(uri, [RelativePath="/v1/events",
            
            Headers = [
                #"Authorization" = "Bearer privatekey",
                #"Accept" = "application/json"
    
            ],ManualStatusHandling={308}
        ])
,

        body = Json.Document(finalResponse)


in body

        in req

I couldn't get around this bug.   It seems .net http doesn't handle 308 Redirects.  Hence not a Power BI issue, moreover a .net issue.
