I cannot seem to get the proper way to call a struct ́s method from within an application. I assume its due to fact that parameters are passed in via an interface{} field but I cant find any information on how to get around it.
I get a panic like this one :
panic: type main.Product has no method GetTicker (1:11)
| MyProduct.GetTicker()
| ..........^
Can you please advise ? Here ́s a sample code snippet

type Product struct {
Ticker string
}
func (p *Product) GetTicker() string {
return p.Ticker
}
type Env struct {
+ MyProduct *Product
- MyProduct Product
}
func main() {
code := `MyProduct.GetTicker()`
program, err := expr.Compile(code, expr.Env(Env{}))
if err != nil {
panic(err)
}
env := Env{
+ MyProduct: &Product{
- MyProduct: Product{
Ticker: "PETR4",
},
}
output, err := expr.Run(program, env)
if err != nil {
panic(err)
}
fmt.Println(output)
