Is this a bug report?

Yes.

Did you try recovering your dependencies?

Yes.

Environment

1. node -v: v8.4.0
2. npm -v: 5.8.0
3. yarn --version (if you use Yarn): 1.3.2
4. npm ls react-scripts (if you haven’t ejected): react-scripts@2.0.0-next.b2fd8db8

Then, specify:

  "last 2 Safari versions",
  "last 2 FireFox versions",
  "last 1 Edge versions",
  "not dead",
  "last 2 iOS versions",
  "last 2 Android versions"
]

2

• yarn build - no errors, everything seems OK.

3

• serve -s build and open http://localhost:5000 in Chrome 41.

Expected Behavior

Actual Behavior

• Getting Uncaught SyntaxError: Unexpected token ILLEGAL error in Chrome 41.
• Modern Chrome (65) has no issues.

I have referred to the StackOverflow answer and went through the minified searching for weird characters and found none. I have also "beautified" the code and found no issues with it.
