I get this error “HTTP Error 404.3 - Not Found. The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.” (Handler: StaticFile, Error code: 0x80070032), while requesting a .json file.
Try this url to see the error
I definitely need to support .json files. How can I add a .json mime map?
