I run command
adb reverse tcp:8081 tcp:8081 & react-native run-android
then it worked on debug but when build release apk, app crashed

It looks like your issue may be incomplete. Are all the fields required by the Issue Template filled out?

If you believe your issue contains all the relevant information, let us know in order to have a maintainer remove the No Template label.

Im getting the same error but on index.android.bundle

[react-native-bot]

If you are still encountering the issue described here, please open a new issue and make sure to fill out the Issue Template when doing so.

[vance-liu]

same error! How to fix this?

[nikkwong]

Same error—showstopper. Would love some assistance, please.

[shi-zeyu]

yes,i need some assistance

[harrybui2804]

I'm fixed this issues
this error of react-native-google-maps-services

1. change index.js in node_modules/react-native-google-maps-services/lib/index.js
exports.createClient = function(options)
   to
   export function createClient(options)
2. using it

import {createClient} from 'react-native-google-maps-services'
var googleMapsClient = createClient({
  key: 'your API key'
});

if you using google-maps-services-js, you can fix as same

[egemon]

@react-native-bot please reopen

[martincarrera]

Any fix, update, workaround, something that could help prevent this issue?

Thanks!

[Ankarrr]

I encounter the error too. Then I start "Remote JS Debugging" and the error disappear.

[Rafolo78]

Same error here. Anyone solved this?

[pablen]

As I understand it, the root of these sort of problems is explained here.

More specifically when it says (bold is mine):

When using React Native, you're going to be running your JavaScript code in two environments:

• In most cases, React Native will use JavaScriptCore, the JavaScript engine that powers Safari. [...]
• When using Chrome debugging, all JavaScript code runs within Chrome itself, [...]. Chrome uses V8 as its JavaScript engine.

While both environments are very similar, you may end up hitting some inconsistencies.

So, the confusing part about getting an error if the debugger is closed and not getting it when the debugger is running may be explained by that.

Also consider the syntax error is found by the JavaScript engine itself in the bundle and not by the compiler/bundler in your source code, so that is the reason why the line number mentioned in the error message might not correspond to any of your source files. I think in general these errors are caused by some dependency package not being strictly transpiled ES5 code, so it will run in some environments and not in others.

What I've found useful in such scenarios is generating the bundle manually running something like

react-native bundle \
    --platform android \
    --dev true \
    --entry-file index.js \
    --bundle-output android-debug.bundle \
    --sourcemap-output android-debug.bundle.map

And then in the generated android-debug.bundle file looking at the line number mentioned in the error message (88794 in the OP screenshot). There you should find the offending code.

I upgraded "react-native-elements" from "0.19.0" to "1.10" then i had this problem. I had revert back to "0.19.0" then my app works fine. I did as @pablen said, but i still not found the problem.
