Error Backup Dropbox

[javierpomachagua]

Hi,
I have followed many tutorials for integrating Dropbox to Laravel-Backup but I have this error when I run php artisan backup:run.
What could be happen? I have in order the packages and service providers like Spatie Dropbox in the last version.

Starting backup...

   TypeError

You are misdeclaring the adapter, there is a breaking change on laravel 9
