Meteor build error - unexpected token A

I’m trying to build my app with:

meteor build ~/Projects/my-app-deploy/android-build --server --mobile-settings mobile-config.js --verbose

and I’m getting the below error.

What could be the issue?

Getting installed version for platform ios in Cordova project
Preparing Cordova project from app bundle
Processing mobile-config.js
Copying resources for mobile apps
Writing new config.xml

SyntaxError: Unexpected token A
