Good Afternoon,
i have problems build our app in prod mode. in dev mode using --dev it compiles.

The error looks like:
[16:05:00] lint finished in 2.16 s
[16:05:17] ngc error: Error: Error at /projects/e-pos/epos-service/.tmp/app/app.module.ngfactory.ts:465:68: Supplied parameters do not match any signature of call target.

[16:05:17] ngc error: Compilation failed
As i did not found any other posts about it, i guess i made something wrong".
I have no idea where to look for the error in the app.module file. Its pretty big and looks ok for me.
Any help appreciated :slight_smile:

I also have same issue :frowning:

i had the same problem. for me it had to do with ngOnchange

had it

ngOnchange() {
// do something
}

the compiler expected a peremeter but got none

working one

import { Component, OnInit, OnDestroy, Input, Output, EventEmitter, ViewChild, OnChanges, SimpleChanges } from '@angular/core';

  ngOnChanges(changes: SimpleChanges){
    //do somehing
}

your problem might be diffrent, but i believe it has to do with breaking changes form rc4 to angular final

Thanks for the reply.
Yes that was the case in some of the functions and already resolved. For example with the pipes i had to make the args parameter non-mandatory adding the ?.
In case of the app.modules i anyway do not find the issue until now. I am sure it has to do with the AOT Compiler as in dev mode it compiles and runs wine.
