Angular AOT unknown identifier undefined

Question

I'm trying to run AOT compilation on my Angular project but when I run the command

"./node_modules/.bin/ngc" -p tsconfig-aot.json

I got the following error:

Error: Internal error: unknown identifier undefined
    at Object.importExpr$$1 [as importExpr] (..\node_modules\@angular\compiler\bundles\compiler.umd.js:24071:23)
    at tokenExpr ..\node_modules\@angular\compiler\bundles\compiler.umd.js:18428:39)

    at Array.forEach (native)
    at AotCompiler._compileImplFile (..\node_modules\@angular\compiler\bundles\compiler.umd.js:23916:19) Compilation failed

How can I know in which file the error is and what is the error?

@yurzui What do you mean by reproduction? This is a quite large project, based on Jhipster, and I don't know where to start debbuging — Paulo Henrique de Siqueira, Oct 15 '17 at 04:37
Seriously how do one debug this issue in a big app? The error should have more information. @PauloHenriquedeSiqueira how did you solve this issue? — Shyamal Parikh, May 02 '18 at 08:07

We had the same problem recently for us it was a missing Location import from the @angular/common module.
