Java SDK getting "Invalid authorization value in HTTP header/URL parameter"

It looks like you're using this constructor, where you provide the DbxRequestConfig and an access token String. That is fine and should work. To confirm, I tried this condensed version of your code, with the latest v6.1.0 of the Dropbox Java SDK:

DbxRequestConfig config = DbxRequestConfig.newBuilder("TMS/1.0").build();
String token = "<REDACTED>";
DbxClientV2 dropboxClient = new DbxClientV2(config, token);
FullAccount account = dropboxClient.users().getCurrentAccount();
System.out.println(account.getName().getDisplayName());

That worked successfully for me. You may want to also try this basic version to see if this works for you to try to narrow down where this is breaking in your setup.

And I see you mentioned checking that 'token' was set properly for you originally, but I recommend stepping through the rest of your process to see if/where something may be getting changed. We can't provide support for Beans or autowiring though, as that's not made by Dropbox.

For reference, there are a number of ways of using the Dropbox app authorization functionality, and exactly how you set it up will depend on your scenario and requirements. I recommend referring to the following resources for more information:
