Uncaught (in promise): Error: No provider for ConnectionBackend!

Ionic Framework ionic-v3
1

I am trying to solve this issue since last 3 days but not able to find out any solution for this.

Every time when ever I’m importing HTTP in my .ts file it is showing error “”.

Packages.js

“dependencies”: {
“@angular/common”: “4.1.0”,
“@angular/compiler”: “4.1.0”,
“@angular/compiler-cli”: “4.1.0”,
“@angular/core”: “4.1.0”,
“@angular/forms”: “4.1.0”,
“@angular/http”: “4.1.0”,
“@angular/platform-browser”: “4.1.0”,
“@angular/platform-browser-dynamic”: “4.1.0”,
“@ionic-native/core”: “^3.8.0”,
“@ionic-native/geolocation”: “^3.8.0”,
“@ionic-native/splash-screen”: “3.7.0”,
“@ionic-native/status-bar”: “3.7.0”,
“@ionic/storage”: “2.0.1”,
“ionic-angular”: “3.2.1”,
“ionicons”: “3.0.0”,
“rxjs”: “5.1.1”,
“sw-toolbox”: “3.6.0”,
“zone.js”: “0.8.10”

See the error screenshots.

Please help me to resolve this issue as this is very much critical for me.

Is there a provider for ConnectionBackend?
What exactly are you trying to do anyway?

Go to your app.module.ts

import { ConnectionBackend } from '../providers/connection-backend'; // The exact route

@NgModule({
  providers: [
    ConnectionBackend,
    {provide: ErrorHandler, useClass: IonicErrorHandler}]
})

I disagree with the previous post, and suspect that OP has Http in their app module’s providers array. Get it out of there.

Issue got resolved after importing HttpModule in module js file.
