I recreating my ionic5 app on new macbook but I have issue to build my app.

[Error] Failed to load resource: The requested URL was not found on this server. 
(toSubscriber.js.map, line 0)

How can I debug my app and catch the error?

What happens if you just run “ionic serve” ?

ionic serve works successfully

Delete the ios folder and add the platform again.
Are you using capacitor?

No. I’m using cordova. I setup again my project start by git clone and it works. The problem is caused from google plus plugin.

I receive error on google sign in (401 client id not found). So I removed google plus plugin, reinstalled it using my reverse code id but then build fails.

Very strange.

cordova plugin remove cordova-plugin-googleplus -variable REVERSED_CLIENT_ID=com.googleusercontent.apps.yyyyy-xxxxx

cordova plugin add cordova-plugin-googleplus --save -variable REVERSED_CLIENT_ID=com.googleusercontent.apps.yyyyy-xxxx

During plugin installation I have this error on POB script

Failed to install 'cordova-plugin-googleplus': Error: pod: Command failed with exit code 1 Error output:

it build but I receive blanck screen

@ciccilleju could you please help me?

Thanks

I suggest to migrate to capacitor, you will forget about all this kind of problems

I’m worried on migration. Is it complex?

Not at all but my suggestion is saving a copy of your current project to a new folder and doing the migration there
