Current behavior

When getting the error: “Cannot assign to a reference or variable!”:

• with ng b --aot or ng b --prod: The error consists of ERROR in Cannot assign to a reference or variable! with no line number or file. The following error is the entire module failing to be resolved.
• with ng b: The error occurs at runtime instead, giving a Unhandled Promise rejection: Cannot assign to a reference or variable! ; Zone: <root> ; Task: Promise.then ; Value: Error: Cannot assign to a reference or variable!, and the stack trace points at vendor.bundle.js.

Expected behavior

When getting the error: “Cannot assign to a reference or variable!”, there should be a file and line number associated with the error.

At the very least, including a component name with the error would suffice in my case.

Minimal reproduction of the problem with instructions

plunker link. Error shows up in console, but doesn’t point the the source of the problem.

What is the motivation / use case for changing the behavior?

Errors should point towards the thing that caused the error. Especially useful since I’m pretty sure I have this error in many places.

Please tell us about your environment:

• Angular version: 4.1.3

• Browser: all

• Language: TypeScript 2.1

• Node (for AoT issues): node --version = v6.10.2

This continues to be an issue in Angular 8

The error occurs when "fullTemplateTypeCheck": true in tsconfig.json.

It’s not possible to find out the error, when you have no stacktrace. 😦.
