Issue is not resolved, this is a workaround. We should'nt have to downgrade or change moment import.

I spent some time investigating it and it's most-likely an issue with build-angular like mentioned above. I've narrowed it down to somewhere between 0.900.3 and 0.901.0-next.4. The issue comes from the following lines:

var Jg = n("wd/R");
const Zg = _rollupMoment__default || Jg

Compared to the ones from a working version:

Ng = n("wd/R"),
Vg = n.n(Ng).a || Ng

I'm transferring the issue over to the correct repo.

Same problem

@JosepAlacid the issue is fixed by this PR #17364. We'll release the fix on Wednesday.
