v15 update broke my build - browserlist problem

[StephenFluin]

Command

serve

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

v14 latest

Description

I had a working v14 application I'm trying to update to v15. I ran ng update @angular/cli@next @angular/core@next @angular/material@next (with --force for some old unrelated incompatible packages).

Now when I attempt to ng serve I get the error below related to browserlists. I don't maintain or need any browserslist features, this came from earlier versions of Angular. I tried removing the file and that didn't change anything.

The reported error message touches on rxjs and angular-devkit and doesn't give me enough information to debug or fix this myself.

Minimal Reproduction

clone https://github.com/StephenFluin/baby-log/tree/stephen/v15-2
yarn
ng serve

Exception or Error

baby-log$ ng serve
