I'm getting the same error on a webpack powered project.
I precisely don't know what happened, but I noticed that with this tip something was changing with my TypeScript compilation.
To resolve your same issue (that exact errors on browser console) I have tried this other solution and it worked.
So I think that the issue is something related on how the bundler treat that .mjs extensions

I am having this same issue. I am not sure how to modify the webpack-config.js in an angular-cli project.

If anyone has any more detailed insight it would be greatly appreciated.

I wanted to give amplify a try but it does not work with angular v6
