SharePoint Online - Issue with REST API call on a List exceeded the threshold limit
I have a List in a SharePoint Online site collection which has exceeded 5000 items. I have indexed the columns that are needed in the REST API filter query during list creation itself. Below is the Rest API query I use to fetch the data from the list. https://people1v02.sharepoint.com/sites/spfxqaw44/_api/web/lists/getByTitle('Announcements')/items?$top=4999https://people1v02.sharepoint.com/sites/spfxqaw44/_api/web/lists/getByTitle(%27Load%27)/items?$filter=Title&xsdata=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&sdata=eXFZS28xbGZvcCtOWmN0MW5yZjBvMjNZWFdVdURMakxRVTNEWEwyN29tRT0%3D&ovuser=5f07e555-d998-4900-b5c4-903fae306283%2Cnagarajan.muthukumar%40eleviant.comhttps://people1v02.sharepoint.com/sites/spfxqaw44/_api/web/lists/getByTitle('Announcements')/items?$top=4999 &$filter=(Expires ge '2022-12-06T18:30:00.000Z') and (RecordDate le '2022-12-06T18:30:00.000Z') and IsActive eq 1 and WorkflowCompleted eq 1 &$select=Id,Title,Expires,ShortDescription,Created,RecordDate,Attachments,LangTrans&$expand=AttachmentFiles&$orderby=RecordDate desc The above query gave me an error as threshold limit exceeded. So I have created a simple list and made a API call as below, https://people1v02.sharepoint.com/sites/spfxqaw44/_api/web/lists/getByTitle(%27Load%27)/items?$filter=Title&xsdata=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&sdata=eXFZS28xbGZvcCtOWmN0MW5yZjBvMjNZWFdVdURMakxRVTNEWEwyN29tRT0%3D&ovuser=5f07e555-d998-4900-b5c4-903fae306283%2Cnagarajan.muthukumar%40eleviant.com ne 'Load Test'&$top=4999 Generally the return data count should be 4999 but I am able to get only 4970 items as response data. Also this response count is unpredictable, for some other lists I got response count less than 4000. Any idea on this inconsistent behavior?
