MS Graph The request is unprocessable because it uses too many resources

[ComNeuf8871]

I have added content types to the drives and try now to find a file based on a value in the column "MARIMPBELID" via a filter Odata request

drives/{drive-id}/list/items?$filter=fields/MARIMPBELID eq 100400

At one client I get a result:  {"error":{"code":"notSupported","message":"The request is unprocessable because it uses too many resources","innerError":{"code":"tooManyResources","date":"2022-09-22T11:27:32","request-id":"xxx","client-request-id":"xxx"}}} 422 GET: https://graph.microsoft.com/v1.0/drives/xxxx/list/items?$filter=fields/MARIMPBELID eq 100400

@ComNeuf8871 

Did you try adding a header prefer: HonorNonIndexedQueriesWarningMayFailRandomly to your request as mentioned at: Microsoft Graph returns 422 error on querying for specific SharePoint list items 

Can you try and let us know if this works for you?

@ComNeuf8871,

Also, try adding indexing on "MARIMPBELID" column as mentioned here: Graph query on SharePoint Library with Paging 

Documentation: Add an index to a list or library column
