Hi Claus
It looks like that dropbox will now only issue short-lived access tokens and
working with additional refresh tokens.
From dropbox doc:
On September 30th, 2021, Dropbox will retire the creation of long-lived access
tokens. Apps that require background (“offline”) access but have not yet
implemented refresh tokens will be impacted.
Implement refresh tokens: For apps that "Want to interact with the Dropbox API
when a user isn’t actively interacting with the app (“offline” access)", we
offer a long-lived refresh_token that can be used to request a new, short-lived
access token.
I think there must be an adjustment in the API Camel is using.

Hi
Ah is that because your token is some kind of developer token that is short
lived?
Or do you know if its standard at DropBox to have tokens limited to 4 hours?
If its so short lived, then we should look at a way for Camel to be able to
automatic extend the token expiry, fetch a updated token, or what means DropBox
supports.
