Unable to match data on map[string]struct

[simonvadee]

I'm having an issue when executing a JMESPATH query on a map[string]customType, here's the code :

type testStruct struct {
	Value interface{} `json:"value"`
}

func main() {
	test1 := map[string]interface{}{
		"entry": testStruct{Value: 1},
	}
	result1, err := jmespath.Search("entry.value", test1)
	fmt.Printf("\nerr = %v : res = %+v\n", err, result1) // displays err = nil : res = 1

	test2 := map[string]testStruct{
		"entry": testStruct{Value: 1},
	}
	result2, err := jmespath.Search("entry.value", test2)
	fmt.Printf("\nerr = %v : res = %+v\n", err, result2) // displays err = nil : res = nil
}

As you can see, a query on a map[string]interface{} behaves as expected, whereas nil is returned when executing the same query on a map[string]testStruct (adding a pointer to testStruct results in the same output).

Has anyone ever experienced such a problem ?

I'm experiencing this same thing with a map of string to a primitive type e.g. map[string]string or map[string]int. When I use map[string]interface{}, it works fine as you stated. In the other cases, the search always returns nil.
