[Solved] React Native Error: No bundle URL present

Updated: February 12, 2023 By: A Goodman Post a comment

This article shows you a few solutions to fix the No Bundle URL Present error when working with React Native.

The Problem

When developing an iOS app with React Native, you might run into the following error:

No bundle URL present.

Make sure you're running a package server or have included a .jsbundle file in your application bundle.




You may also notice that the Metro terminal doesn’t launch as it should:

Don’t panic. We have more than one solution to get the issue fixed.


Modifying the info.plist file

By updating the info.plist file, we will allow insecure network connections via localhost, therefore, making the development process works fine again (the info.plist file locates at <your-project>/ios/<your-project>/info.plist).

Add the NSAppTransportSecurity key to the file, then restart your project:



If your info.plist file already contains those things, but the error is still, see the next solution.


This approach seems so silly, but it has a chance to work.

1. Run:

npm start

2. Hit the “R” key on your keyboard.

3. Click on the “Reload” button located at the bottom of your iOS simulator screen:

Accepting Xcodebuild License

Sometimes the error happens because you haven’t agreed to the Xcode license. What you need to do is just executing the following command in your terminal window:

sudo xcodebuild -license

Removing the iOS build folder and killing all React Native sessions

Deleting the iOS build folder:

rm -rf ios/build/

Stopping all React Native sessions:

kill $(lsof -t -i:8081)

Remove the app on the iOS simulator (just for sure):

Run your project again and check the result:

npm run ios

Recheck your entry file

The error may occur due to an incorrect entry file. Make sure that the names of the index.js (or index.ts) and App.js (or App.ts/App.tsx) files are correct. If it is not, update them to the correct file names.


We’ve walked through some solutions to fix an error that commonly occurs when making iOS apps. If you’d like to learn more new and interesting things in React Native, take a look at the following articles:
