Make Sure You're running a packager server or have included a .jsbundle file in your application bundle. (error showing running already build project)

Question

I am running React Native project using npx react-native run-ios in terminal but its showing the following error:

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

RCTFatal 
28—[RCTCxxBridge handleError:]_block_invok e 
_dispatch_call_block_and_release
_dispatch_client_callout
_dispatch_main_queue_callback_4CF 
_CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_Q UEUE 
_CFRunLoopRun 
CFRunLoopRunSpecific 
GSEventRunModal 
—[UlApplication _run]
UIApplicationMain 
main 
start

Solutions I have already tried

Changing port
Downgrading node module
Downgrading both React Native and project
Upgrading Firebase to the latest version and reinstalling it
Killing port if there is any script running

I have tried almost everything online and am looking for a solution.

So [none of these answers](https://www.google.com/search?q=RCTFatal+RCTCxxBridge+handleError+site:stackoverflow.com) helped? — mplungjan, Aug 31 '21 at 11:07
Did you not miss the title of the error, like "No bundle URL present" - then you may have a dupe [here](https://stackoverflow.com/questions/43949607/no-bundle-url-present-react-native) — mplungjan, Aug 31 '21 at 11:09
@mplungjan i have tried this but it did not resolve my issue — Rashid Ali, Aug 31 '21 at 11:26
open dev tools (ctrl + m for ios simulator or shake device if its not simulator), then there in settings some where you can edit ip address, add your computers local ip with port, — Nikhil bhatia, Aug 31 '21 at 12:11

Adding this:

"build:ios": "react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios'"

to my package.json "scripts" worked form me.

In 2022, I faced this issue with "react-native": "0.70.6". I renamed my "index.tsx" file to "index.js" file now it's ok.

and also in app level build.gradle file:

project.ext.react = [
    enableHermes: true,    //clean and rebuild if changing
    entryFile: "index.js", // "index.tsx",
]
