Today POST ../notes/sections/{id}/pages end point fail with error 20280 "Transient error occured while processing request. {0}". Making it impossible to programmatically create a page from user data to onenote. This occurs when directly interacting with the endpoints or via microsoft graph explorer.
the error response data is :
{"code":"20280","message":"Transient error occured while processing request. {0}","innerError":{"date":"2023-10-11T03:37:06","request-id":"4b84b497-b840-4d12-b3e7-35a36f5331ed","client-request-id":"4b84b497-b840-4d12-b3e7-35a36f5331ed"}}
