Build issue with Ivy and CASL

I have tried install CASL for Angular in my project. Unfortunately, when I try to start the application, I get the following error message:

ERROR in /Users/julien/Documents/repositories/frontend/node_modules/@casl/angular/__ivy_ngcc__/dist/es6/index.js
Module build failed (from /Users/julien/Documents/repositories/frontend/node_modules/babel-loader/lib/index.js):

I'm using the latest version of angular "10.0.9". If I disable completely the source maps then the message disappear but it's not really an option during development.

Any ideas ?

Solution

This is a bug in @casl/angular with source maps generation which was fixed in @casl/[email protected]

Now, it works as expected
