Cannot show class tree for a game I bought off Steam

[JohnMackYouTube05]

When I run the command to show the class tree for the one pak file in a UE4 game I got off Steam, your program throws an error. The console dump is below:

C:\Users\liljm\Downloads\ue4pak>ue4pak.exe --colors class-tree -p "D:\Games\Steam\steamapps\common\Arcade Redemption\TokensOnly\Content\Paks\TokensOnly-WindowsNoEditor.pak"

Can anyone help me?

[Vilsol]

@JohnMackYouTube05 Can you upload a full log of the the output when you add --log trace flag?

[JohnMackYouTube05]

@Vilsol here's the full log trace according to the program.

I have the same issue. Here is my golang main.go and the output.

package main

import (
    "context"
    "fmt"
    "os"

    p "github.com/Vilsol/ue4pak/parser"
)

func main() {
    file, err := os.OpenFile("pakchunk1004-WindowsClient.pak", os.O_RDONLY, 0644)
    if err != nil {
        panic(err)
    }
    defer file.Close()

    fmt.Println("file", file.Name(), "opened")

    parser := p.NewParser(file)
    parser.Parse(context.Background())
}

$ go run main.go
file pakchunk1004-WindowsClient.pak opened
panic: End of stream: 221 < 436323551

Nevermind. It is because the pak is encrypted.
