Socket open failed when calling spawn

[tommyjtl]

Hi everyone, I recently started trying out the demo web app. However, when I attempted to use spawn instead of shell, I encountered the following error:

Error: Socket open failed
    at AdbPacketDispatcher.handleClose (dispatcher.ts:172:1)
    at Object.write (dispatcher.ts:94:1)

Here is the modified code, where the code snippet below is placed inside an onClick function for a button:

GLOBAL_STATE.device.subprocess.dispose();
// shell works fine
GLOBAL_STATE.device.subprocess.shell().then(
  action((shell) => {
    // terminal!.socket = shell;
    console.log("shell:", shell);
  }),
  (e) => {
    console.log(e);
  }
);

GLOBAL_STATE.device.subprocess.dispose();
// but I'm not able to `spawn` a command and get the returned output
GLOBAL_STATE.device.subprocess.spawn(`ls`).then(
  action((spawn) => {
    console.log("spawn:", spawn);
  }),
  (e) => {
    console.log(e);
  }
);

Could someone please review my use of spawn and confirm if it is correct? If not, what is the correct way to use it?

My intention is quite simple: I want to execute a command such as ls -l or ifconfig and obtain the stdout and stderr outputs. I am using the default global.ts as a template.

Thanks!
