Uncaught SyntaxError: Unexpected token =" in "function isNumber(value, ignoreNaN = false)

Ionic Framework ionic-v3

Hello,

We’ve an error in the android version of our application (ios and browser versions are ok): “Uncaught SyntaxError: Unexpected token =” in “function isNumber(value, ignoreNaN = false)” (seems the default parameters are not recognized)

Here a screenshot.

Thanks at all for the help.

How exactly are you building your app?

4

We’re trying from win10 and from mac (with android sdk tools, emulator, gradle installed),
The command we use to build is the same for both:

ionic cordova build android
5

So building succeeds, but when you then run the app you have a white screen only and this error message in the console, nothing else?
No extra output during the build that could mean something?

Upgrade this to a current version with npm install --save-dev @ionic/app-scripts and try again.

@Sujan12 thanks for your response.
We’ve solved removing the package causing this problem (typescript-dotnet-es6). Maybe this package was in conflict with the target “es5” defined in tsconfig.json.

Maybe.

Strange that it only affected the Android build…
