Error (400) when open dropbox (request URL)

Hello,

I found a problem when trying to request URL.

I have two apps in dropbox:

  1.  App 1 (status=production), use Permission type = Full Dropbox

  2. App 2 (status=development), use Permission type = Scope App

I've implemented short-lived token in App 2 (Scope App). I add all scope in scope requests according to permission in App 2.

DBScopeRequest *scopeRequest = [[DBScopeRequest alloc] initWithScopeType:DBScopeTypeUser
                                                                    scopes:@[@"account_info.read", "files.metadata.write", "files.metadata.read", "files.content.write", "files.content.read", "sharing.write", "sharing.read", "file_requests.write", "file_requests.read", "contacts.write", "contacts.read"]
                                                      includeGrantedScopes:NO];

When use the code above, my app success to show the login page.

But when I use the code above to App 1 (Full Dropbox). I get the error page ("scope": must be at most 0 characters, got 192)

Why that's happened? is it because App 1 is already "full dropbox"?
I've tried to delete all scope in scope requests, and can open sign in page. Can you explain?
