Check if a value is an int

Question

So Im sending this payload to my app :

{
    "name" : "Matias Barrios",
    "age" : 123
}

The problem I am facing is that when I test if name is a string it works perfectly. But test if age is an int is always returning false, no matter what I do.

if gjson.Get(spec, "name").Exists() {
            if _, ok := gjson.Get(spec, "name").Value().(string); !ok {
                n := validator_error{Path: "_.name", Message: "should be a string"}
                errors = append(errors,n)
            }
}

if gjson.Get(spec, "age").Exists() {
            if _, ok := gjson.Get(spec, "age").Value().(int); !ok {
                n := validator_error{Path: "_.age", Message: "should be an int"}
                errors = append(errors,n)
            }

        }

Could someone tell me where is the error here?

Note - I am using this https://github.com/tidwall/gjson to get the values out of the JSON.

It seems like this lib for json numbers it return float64

bool, for JSON booleans
float64, for JSON numbers
string, for JSON string literals
nil, for JSON null
