Any solutions ?

I also ran into this error. This is a pretty big json file, so it would be helpful to know which value is causing the error. Please advise.

In my case, this was caused by having a custom action that does not use a standard DRF renderer to return a StreamingHttpResponse instead of something more standard like application/json so Swagger couldn't figure out the mime type of the response and it left an entry like this:
"produces": [""]

The swagger2markup tool did not like this so it bailed. I fixed this by manually changing the above to just read:
"produces": []

But probably it is better to specify the actual mimetype you expect to return in your response.
