I have referenced the solution provided in this GitHub issue, but it does not solve my problem.

Below is my launch.json configuration:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: /?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${workspaceFolder}",
            "debugAdapter": "dlv-dap"

        }
    ]
}

The panic occurs at the beginning of the main function, but the message is not shown graphically.

How can I resolve this issue and display the panic messages correctly?

Call stacks:

runtime.fatalpanic (\usr\local\go\src\runtime\panic.go:1294)
runtime.gopanic (\usr\local\go\src\runtime\panic.go:806)
main.main (\home\welco\go\projects\test\main.go:4)
runtime.main (\usr\local\go\src\runtime\proc.go:283)
runtime.goexit (\usr\local\go\src\runtime\asm_amd64.s:1700)

• Please do not post picture of text. – Volker Commented 15 hours ago
• @Volker What does it mean? The picture is simply to show that the PANIC message is not being displayed graphically. How can I post the content of this picture as text? – hyunseo welcome Commented 15 hours ago
• What do you mean by "ANIC message is not being displayed graphically" you got the panic and the call stack (bottom left). – Volker Commented 13 hours ago

you can try to use

{
  "version": "0.2.0",
  "configurations": [{
      "name": "Launch Package",
      "type": "go",
      "request": "launch",
      "mode": "debug",
      "program": "${workspaceFolder}",
      "debugAdapter": "dlv-dap",
      "dlvFlags": ["--log"],
      "showLog": true,
      "dlvFlags": ["--log"],
      "logOutput": "debugger,debug",
      "showReturnValue": true
    }]
}

or try to utilize recover()

func main() {
    defer func() {
        if r := recover(); r != nil {
            fmt.Fprintf(os.Stderr, "Recovered from panic: %v\n", r)
        }
    }()

    panic("This is a panic!")
}
