Unable to deploy: An unhandled exception occurred: Project target does not exist.

**Describe the bug**
I am trying to deploy a sample angular app as per the instructions given [here](https://github.com/Azure/ng-deploy-azure).

**To Reproduce**
Steps to reproduce the behavior:
1. Follow the below steps as in to [this tutorial](https://docs.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-angular) create a new angular app
```
npm install -g @angular/cli@8 # Install the Angular CLI
ng new iam-spa --routing=true --style=css # Generate a new Angular app
cd # Change to the app directory
npm install @angular/material@8 @angular/cdk@8 # Install the Angular Material component library (optional, for UI)
npm install msal @azure/msal-angular # Install MSAL and MSAL Angular in your application
ng generate component home # To add a new page (such as a home or profile page)
```
2. Run `ng serve` to launch the app and see if it is created alright.
3. Add ng-deploy to your project
`ng add @azure/ng-deploy`
4. Deploy your project to Azure.
`ng run iam-spa:deploy`
5. When I run the above command, I am getting the below error:
> An unhandled exception occurred: Project target does not exist.
> See "C:\Users\username\AppData\Local\Temp\ng-QzVaez\angular-errors.log" for further details.

I tried the same steps by creating a new service-principal with role contributor and login with it. But, no luck. Please check
