`wails3 generate bindings -ts ` go an error when multi struct on another package (not main)

[DreamFlyC]

Description

go version: 1.21.7 wails3 version: v3.0.0-alpha.4

I created a project using the command wails3 init -n wails3-firstapp -t vue-ts 。 then use wails3 generate bindings -ts got an error.

To Reproduce

create file：oth/other.go.

package oth

type OtherService struct {
}

type Person struct {
	Name string `json:"name"`
}

func (g *OtherService) Other(name string) *Person {
	return &Person{Name: "Hello " + name + "!"}
}

---

then use wails3 generate bindings -ts.

wails3 generate bindings -ts
