Remote debugger bug, react-native v 0.50 android

Is this a bug report?

yes

Environment

Environment: OS: Linux 4.10 Node: 8.5.0 Yarn: 1.0.1 npm: 5.3.0 Watchman: Not Found Xcode: N/A

Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed) react: 16.0.0 => 16.0.0 react-native: 0.50.4 => 0.50.4

Browser: Chrome Version 59.0.3071.115 (Official Build) (64-bit) Target: (Android 8.0)

Steps to Reproduce

react-native init AwesomeProject cd AwesomeProject react-native run-android enable remote debugger on device

open browser to http://localhost:8081/debugger-ui/

Expected Behavior

device should connect to remote debugger with no errors

Actual Behavior

device will not connect to remote debugger.

console will display -

‘Uncaught SyntaxError: Unexpected token …’ localhost/:183

localhost/:183 -
worker.postMessage({ …object, url: await getBlobUrl(object.url), });

I reverted back to 0.49 and it got rid of the error, and am able to connect properly, so I am sure it is with 0.50

it looks like the error is coming from object spread operator in /react-native/blob/master/local-cli/server/util/debugger-ui/index.html

Object spread is not supported pre version 60 on google chrome.

Reproducible Demo

react-native init ${app name}

I have a bugfix in my repo, I submitted a PR as well.

You can pull down my version instead of the facebook one

Another fix ( if you are using chrome ) , upgrade to the latest version of chrome
