The error is:

It happens on an ngw serve, probably also the other commands.

Downgrading to cli v6.1 fixes it.

[splincode]

Please add more information

[larssn]

I did just that. There's not much to go by.

[ivanpadavan]

There is enough to go by. Even up to solve the problem :)

[akaiserg]

Same problem, I had to fixed the version of cli to 6.1.4. Besides I tried to use @angular-builders/custom-webpack:browser but I got the error "SyntaxError: Unexpected token export" When I was building the app.

[alex88]

Not sure if it's an issue just with 6.2.*, I've downgrade just the CLI to 6.1.5 and I get the same error. Angular core/etc version is 6.1.8

Nvm, my problem, forgot to do the setup step

Update 2: after doing the setup and fixing the angular.json for 6.1.x CLI the above error is still there using @angular/cli 6.1.4:

You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

Update 3:

The trick was to downgrade @angular-devkit/build-angular to 0.6.7 (as the package.json of this tool suggests), this solves the above issue but creates this in the ngw.config.ts file:

export default function (config, options) {
^^^^^^

@larssn could you please post your package.json to see which of your dependencies fixes the problem?

Update 4:

Changing "module": "es2015", to "module": "commonjs", fixed the unexpected token export issue

[n-lavrenko]

Thank you @alex88 for the Update 4
