                        alert("Product successfully created!");
                        this.props.getProducts();
                        this.props.setVisibility(false);
                    } else if (data.code == 401) {
                        alert("Your product limit has exceeded!");
                    } else {
                        throw "error";
                    }
                })
                .catch((err) => {
                    throw err;
                });
        }
    } catch (err) {
        alert("Error creating. Try Again Later!");
        console.log(err);
    }
}

what should i do?

I think the promise is failing and not able to find an error block. You will have to add a catch statement with the promise.

promise
.then((res) => {})
.catch(err => console.log(err));
