Crash when extension watchlist specified in package.json

See original GitHub issue

nodemon -v: 2.0.2
node -v: 13.0.1
Operating system/terminal environment: macOS 10.15.3 / Hyper 3.0.2
Using Docker? What image: NA
Command you ran: nodemon .

Expected behaviour

nodemon is expected to run with the given parameters I have in nodemonConfig, as specified later in the issue.

Actual behaviour

nodemon fails to start, throwing the error seen below.

Steps to reproduce

Add ext array (with some extensions) to nodemonConfig in package.json. Here’s an example, taken straight from my package.json:

"nodemonConfig": {
    "ignore": [
      "sessions/*"
    ],
    "ext": [
      "js",
      "scss",
      "hbs"
    ],
    "verbose": "true"
  }

Run nodemon .

If applicable, please append the --dump flag on your command and include the output here ensuring to remove any sensitive/personal details or tokens.

It seems the extension list should be specified as a comma-separated list instead of an array. This works for me:

"ext": "js,json,md"
