I am encountering the same issue with an ionic app. I've noticed that angular/cli v9-rc.13 was working fine but rc.14 then final version 9 threw me the exact same error. Let me know if you need more information

[filipesilva]

Heya, looking into this atm, I believe it's due to a change in https://github.com/angular/angular-cli/pull/16822.

[eun-choi]

Same for me. Build succeeds until version > 9.0.0-rc.14 But, build failes version 9.0.0-rc.14 and 9.0.0

[filipesilva]

Fix incoming in https://github.com/angular/angular-cli/pull/16859, hopefully we can cut a release with it soon.
