This error is because the data type of the date component of Element cannot be Number
Solution: convert data to the string
number type to string type (recommended way two)
Method 1.
var date = toString(2022); // Disadvantage: can't convert underfind and null
Way 2
var date = String(2022); // can convert underfind and null
Way 3
var date = 2022 + ''; // string splicing
