SharePoint site page Graph API endpoint fails with status code 422

Question

Hi,

We've integrated with the beta version of the Graph API, using the below call:

https://graph.microsoft.com/beta/sites/{{siteId}}/pages

Where the "{{siteId}}" variable is the ID of a site in our SharePoint tenant.

Whenever we query this endpoint for one of our sites, we receive the below:

HTTP Status 422:

{
    "error": {
        "code": "notSupported",
        "message": "The request is unprocessable because it uses too many resources",
        "innerError": {
            "code": "tooManyResources",
            "date": "2023-05-02T13:37:57",
            "request-id": "eedfa0a2-a72f-4b50-a571-70a2ac503929",
            "client-request-id": "eedfa0a2-a72f-4b50-a571-70a2ac503929"
        }
    }
}

Is there any way we can circumvent this error? I've tried using pagination in my calls but this doesn't work.

It's worth noting that this works fine for 4/5 sites we've tried internally, but one of these fails. I have a suspicion it's due to the number of pages in the SharePoint site, but these currently cannot be archived down or deleted.
