Realm-js: Crashing in debug mode on Android after upgrading to React Native 0.48.2

[letalumil]

Today I upgraded from React Native 0.47.2 to 0.48.2 and since that moment the app crashes if I do remote JS debugging.
The same behaviour for both Realm 1.10.3 and 1.11.1.

Here are the most interesting lines from logs:

09-11 18:24:59.804 24888-24953/com.myapp V/JSRealm: setupChromeDebugModeRealmJsContext
09-11 18:24:59.826 24888-24953/com.myapp I/Realm: Starting the debugging WebServer, Host: null Port: 8082

09-11 18:25:01.514 24888-24986/com.myapp A/art: art/runtime/java_vm_ext.cc:470]     from java.lang.String io.realm.react.RealmReactModule.processChromeDebugCommand(java.lang.String, java.lang.String)

So it seems that the app crashes on this line.

[kneth]

@letalumil Is it possible for you to add code which can reproduce this crash?

[lijy91]

I have the same problem, I just opened the debug mode.

[letalumil]

@kneth OK, here it is: https://github.com/letalumil/realm-js-1294

But literally, all I did to create the sample project is:

react-native init RealmTest
yarn add realm

Then I run react-native run-android, and after enabling the debug mode the app crashes with the stack trace above. I tested on two Android Studio emulators: Nexus 5 API 23 and Nexus 5X API 24, same issue on both.

[letalumil]

If it helps, I tried to find since which version the problem occurred, and it seems that it's there since the v0.48.0-rc.0 RN version, everything works fine on v0.47.2.

[kneth]

@letalumil To be honest, we haven't tested Realm JS with 0.48.0-rc.0. I guess we'll wait until 0.48.0 has been released.

[letalumil]

@kneth I mentioned version 0.48.0-rc.0 just to let you know when things got broken. Version 0.48.0 has been released 10 days ago, version 0.48.3 has been released yesterday, and the problem persists in all of them.

[kneth]

@letalumil Apparently I have been living under a stone for a while :smile: It sounds like we need a few changes to be compatible with 0.48. I relabel the issue and move it to our backlog so we can put a priority to it. Thanks for bringing it to our attention.

Same thing happend on me, app crashed when turn on debug mode.

Also having the same issue on RN 0.48 and above.

[danielang]

Same issue...

[AdamLenda]

same issue...

[ashwinphatak]

https://github.com/facebook/react-native/commit/c00abe53c3e24218afa694b2b58440403a102fd2 seems to be the reason. The inspector proxy runs on port 8082 in RN >= 0.48 and this interferes with the RPC server Realm uses internally to support Chrome debugging.

I'll try moving the RPC server to a different port and see how that works.

[ashwinphatak]

Chrome debugging works fine for me after this fix. Changes are merged into the master branch.

[prabhu]

Are you planning to release 1.13.0 with this?

[kneth]

@prabhu Yes, I hope to have time early next week to do a 1.12.1 release (or 1.13.0 if we add some functionality as well).

[agersoncgps]

I manually applied the changes from the patch, although my folder structure was slightly different. I now get:

Realm failed to connect to the embedded debug server inside the app. If attempting to use Chrome debugging from a device, ensure the device is reachable on the same network as this machine.

Downgrading to ReactNative 47 to work around it.

[danielang]

When did you release this fix?

[8BallBomBom]

Still waiting on this fix to be released.

[blagoev]

this is already fixed and merged and will be released as part of 2.0
If you want you can backport it in your apps by changing this RealmReactModule.java like so

[AbdulRehmanDevStudio]

Application crashes on android Version 8.0 when i want to enable hot reloading or long press on bottom Navigation buttons of mobile device.

[kneth]

@AbdulRehmanDevStudio But only on Android 8?

[laukaichung]

@agersoncgps @kneth

React Native 0.53
Realm: 2.28
Get the same error when restarting the app on a real device with the debug mode on. I need to switch the app on and off to escape this error, very annoying.

DOMException: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://192.168.1.149:8083/create_session'

````

[kneth]

@stonecold123 And 192.168.149 port 8083 is reachable from the device?
