can someone help me with this?

Answer 1

You should fix that by adding the main entry point for app.
packages: {
app: {
main: 'main.js',
defaultExtension: 'js',
},
rxjs: {
defaultExtension: 'js'
}
}

Answer 2

This is happening because the app/main.js file is missing.
The http-server is returning HTML equivalent to index.html because there is no file to return. This is not the UMD module that zone.js expects, so we are getting a parsing error.
You will need to ignore this error once and proceed with the official guide.
