how to check and store data in mongo

i am trying to store data in MongoDB.Here I am checking whether data is present or not. if data already exists then throwing an error or else storing data. please check the below code in the below data having duplicate data(name and ICC). after saving the first record it should throw an error but here it's not throwing any error.

                    let Records = [{
                        name: 'test',
                        icc: 'testId'
                    },
                    {
                        name: 'test',
                        icc: 'testId'
                    }]
                    await Promise.all(Records.map(async (item) => {
                        try {
                            item['id'] = id
                            let ItemObj = table_name.build();
                            item.name = item.name;
                            item.icc = item.icc;
                            let found = await table_name.findOne({ where: { name: item.name, id: id } })
                            console.log("11111111111111111");
                            if (found) {
                                console.log("22222222222222222222");
                                throw new Error(item.name + " is already exist!");
                            } else {
                                console.log("333333333333333333333333333333");
                                Object.assign(ItemObj.dataValues, item);
                                console.log("4444444444444444444")
                                await ItemObj.save()
                                console.log("5555555555555555555")
                            }
                        } catch (err) {
                            throw new Error(err);
                        }
                    })
                    ).then((data) => {
                        console.log("final");
                    }).catch((err) => {
                        console.log("error logged");
                    })

here flow goes like on console

                11111111111111111
                33333333333333333
                44444444444444444

                11111111111111111
                33333333333333333
                44444444444444444

                55555555555555555
                55555555555555555
