UnhandledRejection: Cannot read property 'range' of undefined

See original GitHub issue

Karma version 5.2.3 Node version 14.15.2

After running the tests Chrome exits and I get the following error:

ERROR [karma-server]: UnhandledRejection: Cannot read property 'range' of undefined
ERROR [karma-server]: TypeError: Cannot read property 'range' of undefined

I suspect this to be related to #3571, node version 14.15.1 works correctly.

Please let me know if I need to provide more information.

I don’t think this issue is in Karma core. From #3571 it looks like the issue is in the @angular-devkit\build-angular plugin. I’ve tested with fresh @angular/cli@11 project and issue is not reproducible. Please consider below options:

stick with older Node version
upgrade to latest Angular
report bug to Angular CLI repository with minimal reproduction if you’re also using Angular 9 as in #3571. Angular 9 is an LTS release, so they may issue a fix.
debug this issue further and figure out if this is a Node regression, then it should be reported to Node itself (which is likely the case given that it broke in the patch release)

In any case, there is nothing we can do on the Karma core to fix issue in the third-party plugin as we don’t develop this plugin.

Happy to re-open if you provide a minimal reproduction showing that this issue is caused by the Karma core.

downgrading from node v15 to v14.16.0 helped, tests are working now
