The error `TypeError: ts_transformer_keys_1.keys is not a function` means that you have failed to get the custom transformer working during compilation. Could you show me how you are using the...

@martnst Sorry for the late response. If you are using Windows, the issue is probably fixed by [this commit](https://github.com/kimamula/ts-transformer-keys/pull/10/commits/8c6145e1735278280ed5c3a2d56e0c27a31caf91). Please try v0.3.1.

@Thanos-Pappas I tested `@angular-builders/custom-webpack` with `ts-transformer-keys` and confirmed `TypeError: Object(...) is not a function` error. I found several issues (such as [this](https://github.com/meltedspark/angular-builders/issues/186) and [this](https://github.com/meltedspark/angular-builders/issues/179)) suggesting that you have to use...

Could you provide a reproduction?
