If you attempt to use the extended JSON parser to deserialize a nested struct, it leaves the fields uninitialized. The following snippet will reproduce the behavior:
package main
import (
"fmt"
"go.mongodb.org/mongo-driver/bson"
)
type Inner struct {
Y string `json:"y"`
}
type Outer struct {
X Inner `json:"x"`
}
func main() {
data := []byte(`{x:":{"y":"foo"}}`)
val := &Outer{}
bson.UnmarshalExtJSON(data, false, val)
fmt.Println(val.X.Y)
}
The expected behavior is that it will print foo, but it actually prints an empty string.
