wsEndpoint() Returning empty string

[0xTushar]

  const browserWSEndpoint = await fakeBrowser.vanillaBrowser.wsEndpoint();

`

// don't know why it is returning an empty string

I've faced with the same and I found out that it uses pipe mode by default (don't know why). Try to turn it off, or add debugging-port=0 to the list of args

Like this

    builder = new FakeBrowser.Builder()
      .deviceDescriptor(dd)
      .vanillaLaunchOptions({
        pipe: false,
      }).userDataDir(userDataDir);
