It looks like someone tried to update the composer dependencies on 14/09/2020 in commit 7db3d6e62c7ab8fa29780354e8d370c49939cdec for issue #143, but didn't update the lockfile. This means the SDK is still running 6.5.2.
Running composer update brings in line with latest (7.4.2) but breaks PHPUnit due to a deprecation/removal on the Psr7\stream_for function. This can be replaced with GuzzleHttp\Psr7\Utils::streamFor().
