@MathieuNls can I ask how did you solve this? I'm getting the same error for browser build and can't figure out how to fix it.

@astec , I changed the way I bundle my lib (https://github.com/Toolwatchapp/tw-core) by using webpack. Then, the main product (https://github.com/Toolwatchapp/tw-mobile) imports this already optimised bundle.
