Saver fails with dataURI
For several years my web-app used the Saver with a dataURI successfully. Recently I discovered that it now fails consistently and returns "null" as error message. Normally the Saver returns an error message like "protocol scheme not supported". Not so with dataURI's. I just get "null".
Here is an example that worked in the past, but does not anymore:
Dropbox.save ('data:,hello', 'hello.txt', options);The error call back in the options just receives "null". Did I miss a policy change concerning supported protocols of the Saver? If so, why not returning a meaningful error message?

Thanks for the report! While it did happen to work previously (at least under a certain file size), the Saver didn't officially support data: URIs. It looks like this did stop working, so we'll look into it. I can't promise a fix though, as it wasn't considered officially supported. If we don't get a fix for this, I'll ask the team to at least clarify the documentation and offer a better error message.
Thanks for your quick reply, Greg.
The server for my web-app is using the unprotected http:-protocol, so I cannot use the core-API (because Oauth requires a https: callback). The Saver is my only refuge for storing relatively small files (music score's) on Dropbox.
Hoping for a fix,

- Greg-DBWe highly recommend setting up TLS on your web app for the sake of security, but if you don't have that set up, but for reference, it is technically possible to still use the OAuth flow without it. You would use the "code" flow but omit the 'redirect_uri' parameter. The user would then need to manually copy/paste the resulting authorization code into your app, which would then exchange it for an access token:
