What did you do?

I have 2 similar versions of the same program. Both work as expected while running the code from terminal. However, version 2 gives the error in vscode even though it still compiles.

Version 1:

package main

/*
#include <stdlib.h>

typedef struct Person {
    char* name;
    int age;
} Person;
*/
import "C"
import (
	"fmt"
	"unsafe"
)

type Person C.Person

func (p Person) PrintName() {
	name := C.GoString(p.name)
	fmt.Println(name)
}

func main() {
	name := C.CString("John")
	defer C.free(unsafe.Pointer(name))

	age := C.int(30)

	cPerson := C.Person{
		name: name,
		age:  age,
	}

	person := Person(cPerson)
	person.PrintName()
}

Version 2:

package main

/*
#include <stdlib.h>

typedef struct Person {
    char* name;
    int age;
} Person;
*/
import "C"
import (
	"fmt"
	"unsafe"
)

func (p *C.Person) PrintName() {
	name := C.GoString(p.name)
	fmt.Println(name)
}

func main() {
	name := C.CString("John")
	defer C.free(unsafe.Pointer(name))

	age := C.int(30)

	cPerson := C.Person{
		name: name,
		age:  age,
	}

	person := C.Person(cPerson)
	person.PrintName()
}

What did you expect to see?

Version 2 of the code should have worked the same way as version 1 in VSCode

What did you see instead?

For version 2, at person.PrintName() it shows

person.PrintName undefined (type _Ctype_struct_Person has no field or method PrintName)compilerMissingFieldOrMethod

Moreover, when PrintName is clicked, it doesn't take to the function.

This is a simplified example of the issue that we are facing in our code base which is not very easy to refactor.
