const config = {
  browser: {
    clientScripts: [],
    timeout: 5000,
    interval: 50,
    loadImages: true,
    switchToNewTab: false,

}

const horseman = new Horseman(config.browser);

horseman

Hey @minhchu this definitely deseveres a new thread. I was able to reproduce the case you posted above.

Also please consider posting all the output, not just the lines describing the error because the lead-up to the error is also very important.

Closing since this is a node-phantom-simple issue and not a horseman one.

See baudehlo/node-phantom-simple#147 for my proposed fix, if you care.
