Refresh access token throws an exception

[BLV2k22]

Hi,

i implemented the DropBox Java SDK 5.4.4 and authorized the client via PKCE Authentication. Credentials are stored in a file.

As documented, the access token is a short living token and the refresh token is the same with every new authentication.

But when client tries to refresh the token (local Spring Boot application was started some hours after authentication) the client throws a DbxOAuthException with DbxOAuthError "unknown". 

Any ideas?

The app in the app console is  in development mode.

Any ideas?

Hi,

it seems i solved the issue. It was a typo in the app secret 😕 Now when i call the refresh method in credentials i am getting a new short living access token,

Best regards
