Getting error with .net/C# on login

[JackLe295]

Hi there,

I'm using the Dropbox .net SDK version 6.24.0 for my winforms application. 

I use this method to get the URL for login 

DropboxOAuth2Helper.GetAuthorizeUri(OAuthResponseType.Token, "client ID", "redirect URI").ToString();

After entering the username, password and clicking Login, I get this message on top of the page

but it let me in and do my usual stuff like browsing folders/files. So what could be causing this error?

Any helps/suggestions are welcome. 

Thanks in advance

Jack

Thanks for the report. There's a known issue causing that message to be shown unnecessarily. The team is looking into it.

By the way, from that screenshot, it looks like your app currently processes the OAuth app authorization flow inside a web view, instead of the system browser. The OAuth app authorization flow should be processed in the user's system browser. Processing it in a web view is not officially supported and is more prone to compatibility issue. See here for more information: https://www.dropbox.com/developers/documentation/http/documentation#oauth2-authorize .

Hi Greg,

Thanks for your response about the known error. With regards to the authorization flow in the system web browser, the application is being deployed on a strict windows server which doesn't allow any other browsers to be installed, it only has Internet Explorer which doesn't support the Dropbox login. That's why I have to use the web view control for it.

That unexpected error message should be fixed now.
