SharePoint API won't return readOnly fields
Hello everyone, we try to get all the attributes from a file in SharePoint using the API. When we call /_api/web/lists(...)/items and filter for the wanted file we get all attributes like name, id, ...
/_api/web/lists(...)/items will not return read-only fields
Here you can use new API to get list items i.e. RenderListDataAsStream which can return read only fields as well.
