Expected behavior

Should migrate to Angular Fire 7 & Firebase 9

Actual behavior

Migration is failing.

Please note that when migrating using version 7.0.1 of the schematics, the migration was successful (after cleaning up the issues related to the schematic updating imports in files outside the project's scope).

Oh interesting, do you mind emailing me your angular.json? [email protected]. I think I know what this is related to but it would suggest there’s something I’m not expecting in there. Thanks.
