Desired functionality.
No error with build optimizer enabled.
Mention any other details that might be useful.
The issue was originally posted in #7797 (comment). I discovered that it is caused by build optimizer and not JIT mode, so creating separate issue for tracking purpose.
I traced it down back to this line. Changing amount of passed to 1 fixes the problem. It is probably a bug in UglifyJS after all, but I don't have enough expertise to trace it down and report correctly in their repo. Maybe somebody else can take it from here.
Relevant code snippet from exception:
bootstrapModuleFactory(e, t) {
const n = function(e) {
let t;
return t = "noop" === e ? new Lr : ("zone.js" === e ? void 0 : e) || new Dr({
enableLongStackTrace: Z()
})
}(t ? t.ngZone : void 0);
return n.run(()=>{
const t = jn.create([{
provide: Dr,
useValue: n
}], this.injector)
, r = e.create(t)
, o = r.injector.get(Wn, null);
if (!o)
throw new Error("No ErrorHandler. Is platform module (BrowserModule) included?");
return r.onDestroy(()=>K(this._modules, r)),
n.runOutsideAngular(()=>n.onError.subscribe({
next: e=>{
o.handleError(e)
}
})),
function(e, t, n) {
try {
const n = (()=>{
const e = r.injector.get(dr);
return e.runInitializers(),
exception here -> e.donePromise.then(()=>(this._moduleDoBootstrap(r),
r))
}
)();
return R(n) ? n.catch(n=>{
throw t.runOutsideAngular(()=>e.handleError(n)),
n
}
) : n
} catch (n) {
throw t.runOutsideAngular(()=>e.handleError(n)),
n
}
}(o, n)
}
