CodePush update does not work with react native iOS app

I'm trying to configure CodePush on my iOS app developed by ReactNative, following these links :

https://microsoft.github.io/code-push/docs/getting-started.html

https://microsoft.github.io/code-push/docs/cli.html

Every single step is configured properly and double checked, but when I trace the process with chrome debugger, the output will be like this :

 [CodePush] Checking for update.                              CodePush.js:159
 [CodePush] An unknown error occured                          CodePush.js:159
 [CodePush] 404: The specified resource does not exist.       CodePush.js:159

Any solution?
