@saeidi-dev Hey 🙂
How is the link you added reproducing the issue? Please add a reproduction repo. You are welcome to open a PR for the fix but I need to understand the scenario where this is happening 👍

@saeidi-dev did you try specifiying the project?

[saeidi-dev]

nx structure

apps
    -myapp
packages
    -i18n // is lib
    

command:

nx g @jsverse/transloco:ng-add --project=i18n

@saeidi-dev Instead of describing the project, can you please create a reproduction repo? you are using nx this should take under 5 minutes to mimic your issue. This is important for debugging and reviewing the solution you want to make in your PR (if you wish to make one).
