MongoDB & Mongoose, Save Nested Array of Objects - Node.js
Can you try to refactor your .post() endpoint like this:
.post(async (req, res, next) => { try { let new_bank_account = await BankAccountsIndexModel.create(req.body); res.status(200).json(new_bank_account); } catch (err) { console.error(err.message); res.status(500).send("Server error"); } })
