Description

When switching the target in tsconfig.json from es5 to es2015 and running `ng build --prod` I get the below error if I try to run the website. The build succeeds.

🔬 Minimal Reproduction

I'm away all weekend and not near a computer. I was asked to re-create this from here: https://github.com/angular/angular/issues/30727. On monday if I have time and it's still needed I will try to get some repro steps.

I had same error. Try npm uninstall --save firebase @angular/fire, then npm install --save firebase @angular/fire. The error has disappeared in my case.

[MathewBerg]

This seems to of fixed itself. Closing.
