[ravisharma]

I am facing below error when I am trying to list folder or get current account info. Please help

Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLKey=https://api.dropbox.com/2/users/get_current_account, NSLocalizedDescription=cancelled, NSErrorFailingURLStringKey=https://api.dropbox.com/2/users/get_current_account}

Below the code I have tried. 

let client = DropboxClient(accessToken: "MYTOKEN")

        client.users.getCurrentAccount().response { (response, error) in

            if let result = response {

                print(result)

            } else if let error = error {

                print(error)

            }

        }

        client.files.listFolder(path: "").response(queue: DispatchQueue(label: "MyCustomSerialQueue")) { response, error in

            if let result = response {

                print(Thread.current)  // Output: <NSThread: 0x61000007bec0>{number = 4, name = (null)}

                print(Thread.main)     // Output: <NSThread: 0x608000070100>{number = 1, name = (null)}

                print(result)

            } else if let error = error {

                print(error)

            }

        }

It looks like your client object is probably going out of scope before the request can finish. Note that the actual API calls are made asynchronously, so the client object may be gone by the time the network call finishes.

Try keeping your client around instead. For example, you can use DropboxClientsManager.authorizedClient.
