Description

After starting Perf Monitor with Dev settings off, React Packager eventually choked without me doing anything with:

Same issue. When I enable Remote Debugger and reload - Particularly when there is a reload after some change is made in a file.

GeoffreyPlitt · 2017-03-17T18:44:40Z

Getting this constantly now.

Having the same exact issue every reload. Using 0.42.0

groke · 2017-03-24T02:34:58Z

edit: I removed each of these plugins one at a time from my installation and the error continues so they don't seem to be the issue

Me too. Maybe a plugin causing it? Do we have anything in common?
"react-native-admob": "^1.2.1",
"react-native-fcm": "^6.1.0",
"react-native-linear-gradient": "^2.0.0",
"react-native-menu": "^0.20.2",
"react-native-splash-screen": "^2.0.0",
"react-native-swipe-gestures": "^1.0.2",
"react-native-timer": "^1.3.1",
"redux-persist": "^4.4.2",

GeoffreyPlitt · 2017-03-24T17:06:10Z

We use react-native-linear-gradient and react-native-swipe-gestures

groke · 2017-03-25T20:50:32Z

I think I found a way around this issue, at least for my setup.
From the development menu on my android I selected Dev Settings and re-enabled JS Dev Mode that resolved this issue for me.

Disable dev mode + Start remote js debuging + Reload = crash
Enabling dev mode does solve it

JosephDev · 2017-04-19T00:07:34Z

I have the same issue on iOS. any solution for iOS?

"react-native": "0.43.3",
"react": "16.0.0-alpha.6",

I face the same issue randomly when developing on real device. (Using adb reverse tcp 8081)

Update: disabling remote JS debugging kinda fixes it.

Same issue. with enabling the remote debugging app crashing on every reload with the same above error

BeckZero · 2017-06-01T06:22:19Z

+1!!
"react": "16.0.0-alpha.6",
"react-native": "0.44.2",

JosephDev · 2017-06-01T15:02:20Z

Here is my solution but I don't know why it works.

remove native codes. ios and android folders. !! backup first !!
rm -rf os && rm -rf android
create a new dummy project.
react-native init AwesomeProject
copy native codes to current project folders

cp -R AwesomeProject/ios currentProject/
cp -R AwesomeProject/android currentProject/

build
modify native codes as you've done on current project for example:

icons, version information, and/or push notification etc...

annelorraineuy · 2017-06-02T22:41:32Z

I am getting this as well.
So on DEV mode ON, chrome debugging works the first time. Upon reload, the app is just a white screen. So I have to turn off Remote JS Debugging in order to get the app back again. Rinse and repeat cycle. :/

"react-native": "0.44.0"
I am using "react-native-navigation": "^1.1.81" though. Not sure if this has something to do with it.

+1!!!! Extremely annoying.

ItsNoHax · 2017-06-29T12:48:10Z

This still happens, has any facebook dev replied to this?

Literally last couple react-native versions have been so crap :(

fredbt · 2017-06-30T16:06:17Z

This is also happening to me. Really annoying.

wuyunqiang · 2017-08-03T07:00:41Z

me too.
android simulator is right. and hardware is bug show me.

RomanISWG · 2017-08-23T14:24:17Z

Same issue by me with
react-native-cli: 2.0.1 react-native: 0.47.2

alzalabany · 2017-10-16T10:07:16Z

any workaround yet ?

WolfieZero · 2017-11-09T10:54:56Z

I've been having this issue, but I can pin-point it to a line.

findContent(block: Block): string {
    const contentBlock = block.descendants[0];

    if (typeof contentBlock.content === 'string') {
        return contentBlock.content; // << Here
    }

    return '';
}

When I change it to return ''; it reloads fine.

JS Dev Mode: off
JS Minify: off
Remote JS Debugging: on
react: 16.0.0-alpha.12
react-native: 0.46.3

lasuax · 2017-11-21T08:15:56Z

Impossible to debug because of this disruptive error.
