Additional context or thoughts

If I hit the endpoint in the browser directly valid JSON is returned. I put the JSON in a validation tool and it came back as being valid. I found a post that indicated that this needed to be added to the web.config:

<add name="Access-Control-Expose-Headers" value="Content-Disposition"/>

That didn’t solve the problem.

This does work in IE11 and Chrome, just not Edge.

Hey, out of curiosity I tried also using Windows 10 with Edge (using version 42 instead of 41 though) and didn’t have any issues with JSON response parsing. I used browserstack which lets you test IE edge for free. Test was against an api using the OAS 3 spec with swagger-ui 3.18.2

@jlw0, glad to hear it worked out!

Closing - on the whole, this seems like an issue caused by an old version of Edge.
