No repository file or test is named; the issue only provides Microsoft Graph request traces from PHP SDK 1.110.0. Start by reproducing the approot lookup and children request, then determine whether the failure is in SDK request construction or the Graph service. Done requires a maintainer-confirmed cause and an explicitly scoped resolution.
