Yaegi interpreter unexpected behavior

[talevy-runai]

Hi,
I've written plugin for jwt validation,

I've used github.com/golang-jwt/jwt/v4

When I'm running Parse token, I get an empty map (only in yaegi test)
go test works fine,

I tried to debug this and I've found out the issue in the line 160

the decode from object return empty string, example object:

I think it doesn't work with the json:"email,omitempty" annotation.

any idea how to manage it?

I'm using yaegi latest

Im experiencing the same here

	parts := strings.Split(bearerToken, " ")
	if len(parts) != 2 || parts[0] != "Bearer" {
		return Claims{}, errors.New("expected authorization header format: Bearer <token>")
	}

	var claims Claims
	token, _, err := a.parser.ParseUnverified(parts[1], &claims)
	if err != nil {
		return Claims{}, fmt.Errorf("error parsing token: %w", err)
	}
	os.Stdout.WriteString(fmt.Sprintf("Token string: %s\n", parts[1]))
	os.Stdout.WriteString(fmt.Sprintf("parsed claims [%v]", claims))
	os.Stdout.WriteString(fmt.Sprintf("parsed token claims [%v]", token.Claims))
	os.Stdout.WriteString(fmt.Sprintf("parsed token [%v]", token))

	payloadBase64 := strings.Split(parts[1], ".")[1]
	payloadJSON, err := base64.RawURLEncoding.DecodeString(payloadBase64)
	if err != nil {
		fmt.Printf("Error decoding payload: %v\n", err)
	} else {
		fmt.Printf("Decoded payload: %s\n", string(payloadJSON))
	}

when manually decoding the payload is there otherwise the claims are empty
