Expected Behavior

The App does not crash on launch and the JS is bundled.

Actual Behavior

The App does crash on launch and the JS is bundled.

Reproducible Demo

React Native 0.48.0-rc.1 does not throw such error and works as expected.
I am assuming that something in here v0.48.0-rc.1...v0.48.0 is causing the issue.

(Paste the link to an example project and exact instructions to reproduce the issue.)

I have the exact same problem. I have been losing my mind for the last few hours. I thought I was the only person in the universe with this problem. Hopefully this get fixed quickly. I need this working for a school project (and time is ticking away).

[larenelg-tw]

Hey @cxgslegend - I had the same problem as well. I'm using a previous version while it gets resolved :)

react-native init --version 0.47.0 <projectname>

[alpfilho]

same problem here

[cxgslegend]

@larenelg-tw, that worked like a charm! Thank you so much!

[joshuabalduff]

Same problem pulling my hair out lol.

[rahulvramesh]

wasted my 2 days. hope it will fix soon.

[kichiwa]

Thank you,
So, I dont need to reinstall node,js,yarn as I think

[masudhossain]

Same problem here. I really wish I looked at the Issues before spending the last 5 hours trying to fix it...

[adithwip]

I think i'm the only one :(
Hopefully it'll fixed soon

[andreatoso]

Same problem here.

[piyush2468]

The New version of react-native is carrying some bugs during js bundle and with gradlew assemblerelease downgrading the react version seems to be only option for right now.

[lcarmichael]

I have the same problem. I have tried 0.47.2, and 0.47.0 with rebuild and I continue to get the same error. I have uninstalled everything from RN to Xcode, hoping that maybe it was a setting that I changed along the way. If anyone has any suggestions as to why downgrading would not work, please let me know.

[lcarmichael]

Fixed by switching to 0.48.0-rc.1 as @fabriziogiordano noted previously. Thank You!

[fredesse]

Ran into the same problem last night so followed @larenelg-tw advice, downgraded to react-native 0.47.0 and that fixed the problem for now. Thanks!

[anivon]

Same problem ! I'm now bald ! :(

[DarkSector]

Same issue. Downgraded to 0.47.2.

[timrc]

+1

[aethiss]

Same issue, solution is downgrade or wait some fix :)

[krittiyaclark]

This is my third days with a same problem. I almost give up learning React-Native.

[fabriziogiordano]

@usakc posted a fix here
#15768 (comment)

I tested it on a fresh blank app and not the iOS Simulator does not crash.

[Jonovono]

React Native is the most extreme love & hate relationship I have.

[kgirma]

@larenelg-tw this is also proven to be stable for both ios and android
react-native init --version 0.47.2 yourprojectname

[srdjanprpa]

Same problem here.

[varunprasadyadav]

Same problem for me also.
What worked is if I create the project using an earlier version like 0.44

[jvitorr]

I am with the same problem
What solution?

[varunprasadyadav]

Use an earlier stable version like 0.44

Same problem here with 0.48.0. I hope a fix will come soon.

[Gotogoo]

This is a bug with 0.48.0,I have the same problem.
I set a exceotion breakpoint with Xcode and find the problem.
The following fixes might be useful to you.

1. open the xxx.xcodeproj with XCode;
2. click ⌘⇧F ,search(in RCTMultipartStreamReader.m at line 79):

NSUInteger headersContentLength = headers[@"Content-Length"] != nil ? [headers[@"Content-Length"] unsignedIntValue] : 0;

3. replace it with:

NSUInteger headersContentLength = headers[@"Content-Length"] != nil ? [headers[@"Content-Length"] integerValue] : 0;

4. run.

#15755 should fix it

[grabbou]

Since I am at the workshop already, I reverted the commit that caused this issue and released 0.48.2.

Apologies for the issues, hope I didn't destroy everyone's Sunday 🔥

[gre]

thanks for your monday morning fix :)

[yudai524]

Thanks !

[srdjanprpa]

@grabbou you mean 0.48.1. Or 0.48.2 coming soon?

[grabbou]

48.1 fixes that issue. Other fixes will land to 48.2

Not yet. I just said all remaining cheery picks will land in next release, which is 48.2 that will happen later this week.
