Cannot read property "toLowerCase" of undefined on release-cordova

[superpikar]

Hello, I'm not sure whether this error is from code-push-cli or cordova-plugin-code-push, since I couldn't find anything related to "toLowerCase" in cordova-plugin-code-push repo.

Following is the description of the problem

Description

I have an existing app built using onsenui+vuejs+cordova, and has no error before.

Then I follows all the step from tutorial https://microsoft.github.io/code-push/docs/cordova.html#link-4, but when I tried to release an update, I got the following error :

Error: Cannot read property 'toLowerCase' of undefined
[Error]  Unable to prepare project. Please ensure that the CWD represents a Cordova project and that the "android" platform was added by running "cordova platform add android".

The complete output of the release-cordova command above are

Reproduction

Clone my project here https://github.com/superpikar/onsenui-vue-cordova-test , then :

# install dependency
npm install

# install cordova plugin
cordova prepare

# build app to /www
npm run build

# release update to codepush, use your own app name
code-push release-cordova onsenui-vue-cordova-test android

Additional Information

This is the installed dependency on my project :

## environment 
node: 6.11.2
cordova: 7.0.1
code-push-cli: 2.1.2-beta

## cordova platform list
android: 6.2.3
browser 4.1.0

## cordova plugins
cordova-plugin-code-push: ^1.10.0-beta

(The more info the faster we will be able to address it!)

I tried to remove all cordova-plugins then running the following command

cordova prepare

I still get the same error

Error: Cannot read property 'toLowerCase' of undefined

Seems like this problem is not related with cordova-plugin-code-push.

Any people here face the same issue?

Nevermind, I was able to solve the problem by starts the project from scratch.
