This is because such a template is invalid:

https://runkit.com/ayazhafiz/ng-parser-badexpression

We must have regressed on not blowing up when we have invalid templates.

[kyliau]

last known good version: v9.0.0-next.3. Regressed starting from next.4 onwards.

changelog: angular/angular@9.0.0-next.3...9.0.0-next.4

The diagnostic message used to be:
