Current behavior

When I run ngcc on a project with transloco I get the following error on the transloco build:

Compiling @ngneat/transloco : main as umd
Error: Expected UMD module file (/Users/timingensiep/Projects/bauhaus/gus-cms/node_modules/flat/index.js) to contain exactly one statement, but found 6.

Expected behavior

It should run without errors.

Minimal reproduction of the problem with instructions

Create Angular 9.1.x Project and add transloco.

For bug reports please provide the STEPS TO REPRODUCE and if possible a MINIMAL DEMO of the problem, for that you could use our stackblitz example

What is the motivation / use case for changing the behavior?

To use Angular with Jest you need to run ngcc to make it work.

I am closing this issue since it seems to be an issue of Angular’s compiler, for those who still have any difficulties I suggest you open an Issue in Angular’s repository.

@giorgi0203 Since you’re specifying your versions with ~ you will get later versions than 9.1.4. Read the previous comments, you need to pin them.
