Name of the primary key is not id

Ajax result if the primary key is not “id”(lowercase) cannot choose example

[
    {
        "Id":1,
        "UserName":"jay1",
        "Age":"18"
    },{
        "Id":2,
        "UserName":"jay2",
        "Age":"18"
    },{
        "Id":3,
        "UserName":"jay3",
        "Age":"18"
    },{
        "Id":4,
        "UserName":"jay4",
        "Age":"18"
    },{
        "Id":5,
        "UserName":"jay5",
        "Age":"18"
    }
]

Just like the above example, if does not contain the attribute “id”(lowercase), select2 will not be able to work, how do I custom primary keys, or when there is no attribute “id” how to make select2 work normally
