1) Handling the /members request using the getMembers method:
mongo.post("/members", async (req, res) => {
try {

mongoDBInstance,
req.body.index,
{ req.body.field },
{pageNumber: req.body.page, pageToken: req.body.pageToken}
);
res.json(result);
} catch (err) { }
});

{field: req.body.field, filter: req.body.filter},
{pageNumber: req.body.page, pageToken: req.body.pageToken}
