DropboxAuthError with error content "expired access token"

[rajubd49]

Our iOS app is basically implemented using Objective C and we use ObjectiveDropboxOfficial to login to dropbox. The app was working fine for a long time, but for the past few days, we are facing an access token expiration issue. If we log in today and try to fetch files the next day, we are getting this error and we need to relink or login again for the dropbox to work.

Error log:

DropboxAuthError[{ ErrorContent = "expired_access_token/"; RequestId = 24a031d6ab81429eb0f714646cbf9f38; StatusCode = 401; StructuredAuthError = "{\n \".tag\" = other;\n}"; UserMessage = nil; }];

What is the solution or best way to resolve this issue?

@rajubd49 It seems like you're experiencing short lived tokens expiring. The Obj-C SDK handles automatic refreshing of expired tokens. Please take a look at the example here for how this is implemented.

@tidrop Thank you for your response, we've solved the issue.

@rajubd49 I am also getting this error Can you show the solved code? Thank you very much!

@tienjp68 My problem was, in podfile we did specified version 3.x.x which was not working anymore for short lived tokens expiring issue. So we've updated ObjectiveDropboxOfficial to it's latest version which is I believe 6.2.3 and it resolves our problem.

@rajubd49 I have reinstalled pod but func "AuthozeFromControllerV2" is not in DBClientsManager+MobileAuth-iOS file, do you know why?

target 'Kodomomenkyo' do use_frameworks! pod 'ObjectiveDropboxOfficial' end

target 'Kodomomenkyo_dev' do use_frameworks! pod 'ObjectiveDropboxOfficial' end

@tienjp68 Note that you have a typo in your comment; make sure you don't also have the same typo in your code. The method is named "authorizeFromControllerV2" not "AuthozeFromControllerV2". The authorizeFromControllerV2 method is defined here in DBClientsManager+MobileAuth-iOS.m.

Make sure you actually have a recent version of the SDK installed, ideally the latest version, which is currently v6.3.2. It looks like you're using CocoaPods, so you can use pod update to update. Check the output to make sure that runs successfully and to check that the latest version is installed.

Then, you can set up the authorization flow as documented.

If something still isn't working as expected, feel free to open a new issue with the details of the issue.
