Receiving error with Office Graph querying a site collection with large number of document libraries

I have a test site collection with 2500 document libraries (I created them using PnP). 

I just tried returning a list of them via Office Graph Explorer but I get an error.

GET: https://graph.microsoft.com/v1.0/sites/<tenant>.sharepoint.com,<site_id>/Lists?$top=10

Failure - Status Code 504, 20312ms

{
"error": {
"code": "UnknownError",
"message": "",
"innerError": {
"request-id": "c1752b49-6dc1-4a18-a3db-d29e4107aca4",
"date": "2018-10-02T21:16:09"
}
}
}

The above GET works on site collection with a smaller number of document libraries.

Thanks for your help in advance.
