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.

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 🔥

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.

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

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

replace it with:

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

run.

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

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.

48.1 fixes that issue. Other fixes will land to 48.2
