@George Ndungu
Thank you for your time and patience throughout this issue!
My team was able to reproduce your issue and see that the request is hitting a limitation, we've raised a bug with the doc author to include this info into our Microsoft Graph documentation - GitHub issue for your reference. There's also a user voice item for the same exact concern, so I'd recommend upvoting this feature to get this looked at by our engineering teams.
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
