expo: The development server returned response error code: 500

Followed this post and updated the sdk to 24.0.0 as I needed expo to support react-native 0.51.0 . Issue 1280

Now when I run npm start everything works fine and when I try to run the app on my moblie using npm start I get this error on console

05:31:06: Finished building JavaScript bundle in 4387ms
05:31:07: Failed building JavaScript bundle

And this on my mobile phone.

I had the same issue here, so what solved my problem was running npm start first and then in another terminal tab run react-native run-android

Downgrade the following: react-native init Project cd Project npm uninstall react-native npm install --save react-native@0.55.4 npm uninstall --save babel-preset-react-native npm install --save babel-preset-react-native@4.0.0 react-native run-android

Same here. Created a new project, run-android, get this in the emulator.

Thanks for the report. We’ve had another report of the same thing, so I am going to consolidate this into that issue. Unfortunately we don’t have a solution for you yet.

delete node_modules folder from project and open package.json change react-native version “react-native”: “0.55.2”, and babel “babel-preset-react-native”: “4”, after that run yarn install or npm install and run.

Hey guys, I got this problem when I installed an npm pkg and removed, what I did to fix was run: react-native link react-native-video
