What is the current behavior?

I get an error when I want to start a crawl. This is the error

This is my configuration file:

{
    "mode": "page-only",
    "depth": 1,
    "seeds": [
        "http://www.facebook.com/nastyvdp",
        "http://www.twitter.com/nvanderperren"
    ],
    "warc": {
        "naming": "url",
        "append": "true",
        "output": "warcs"
    },
    "connect": {
        "launch": true,
        "host": "localhost",
        "port": 9222,
        "userDataDir": "/Users/nastasia/Library/Application Support/Google/Chrome"
    },
    "crawlControl": {
        "globalWait": 60000,
        "inflightIdle": 1000,
        "numInflight": 2,
        "navWait": 8000
    }
}

Because it says that mode is undefined, I also placed mode under crawlControl as suggested in issue #50, but that doesn't solve the issue

What is the expected behavior?

A starting crawl.

What's your environment?

node v14.12.0 Squidwarc: current master macOS High Sierra 10.13.6 Chrome Versie 86.0.4240.80 (Officiële build) (x86_64)

Other information

I don't have this issue if I use puppeteer.

I think this is a just a typo in the mac version of the browser finding code, here is https://github.com/N0taN3rd/Squidwarc/blob/63026b6f4c30b83541f23fc7531126bc7e8747af/lib/launcher/chromeFinder.js#L275

    let sortedExes = installations
      // assign priorities
      .map(inst => {
        for (const pair of priorities) {
          if (pair.regex.test(inst)) {
            return { path: inst, weight: pair.weight }
          }
        }
        return { path: inst, weight: defaultPriority }
      })
      // sort based on priorities
      .sort((a, b) => b.weight - a.weight)
      // remove priority flag
      .map(pair => pair.path)[0]           # <=== this [0] is only in the mac version of this function
    if (sortedExes.length > 0) {
      return sortedExes[0]
    }

Will try to get access to a mac to test changing it to .map(pair => pair.path)
