I'm using google Firestore as my database, I wanted to order my material table by two fields (name and date) so I can have it in alphabetical order + in the date it was created, however I got the following error:

This is my code with "acudiente" being the name of the user and "fecha" being the date of the order and "pedidos" being the collection.

useEffect(() => { 
    const usuariosRef = db.collectionGroup('pedidos')
    usuariosRef.orderBy("acudiente", "fecha").onSnapshot(snapshot => {
      const tempData = [];
      snapshot.forEach((doc) => {
        const data = doc.data();
        
        tempData.push(data);
        console.log(tempData)
      });
      setPedidos(tempData);
    })
   }, []);
