[image] AnupVeerapur: “ionic-native”: “2.9.0”, You don’t need that any more. If your code still uses it, update to the new @ionic-native.

I did as per your instructions @Sujan12 , now I am getting this error below. [19:11:30] build prod started ... [19:11:30] clean started ...

I did update it too. Still the same. [WARN] Error occurred during command execution from a CLI plugin (@ionic/cli-plugin-cordova). Your plugins may be out of date. [DEBUG] !!! ERROR ENCOUNTERED !!! Error: Cannot set property 'fixed' of undefined in undefined at line undefined, col undefined,…
