After a successful upgrade of a library from Angular 8 to Angular 9
when I try to build it I get the following error:
Compiling TypeScript sources through ngc
ERROR: Decorator argument must resolve to a string
An unhandled exception occurred: Decorator argument must resolve to a string
any lead on what can cause this error or what does it mean?
The issues happened because some of the components Output property had a name which was an Enum and not a plain string. once I changed all those places to a string, it solved the issue.

This code is throwing exception
Uncaught Error: Template parse errors: Can't bind to 'ngforOf' since
it isn't a known property of 'mat-card'.
1. If 'mat-card' is an Angular component and it has 'ngforOf' input, then verify that it is part of this module.
div
button(mat-raised-button, color='primary', (click)='createMocked()') Create Mocked
div
mat-card.Class(*ngfor="let room of rooms; let classroomIndex = index; trackBy: trackClass")
if I will add quotes then I'm missing support from Intellij
Does anyone have idea how to fix 1 and 2 or have woking in intellij reference that I can check?
I used this article: https://medium.com/#MarkPieszak/using-pug-or-jade-templates-with-the-angular-cli-9e37334db5bc
The error
Template parse errors: Can't bind to 'ngforOf' since it isn't a known
property
means that Angular template parser tries to find a directive based on your ngforof attribute but it can't since Angular template syntax is case-sensitive.
You have to write *ngFor= so it will converted to ngForOf and Angular will be able to find dedicated ngForOf directive.
If you're curious how Angular transforms structural directives into ng-template syntax then check this out:

I am in the process of migrating an application to Angular 6 from Angular 5. at this point I believe I have most issues sorted out and when building with ng serve or ng build main it builds as expected. however when building as ng build --prod main I get the below error

I have two questions from this
What does this Error actually mean
How do I find it and correct it
Migrating from angular 6.0 to 7.0, I enabled ivy compiler and I got the same error.
Disabling ivy option, AOT build works again.
I'm using FFImageLoading.Cross.MvxCachedImageView and trying to make conditional binding in iOS, but it fails with the following Mvx trace:
Problem seen during binding execution for binding Image for MvxValueConverterValueCombiner combiner-operation - problem ArgumentException: Object of type 'System.String' cannot be converted to type 'UIKit.UIImage'.
Does anyone know what could be wrong?
set.Bind(imgInfo)
.For(x => x.DataLocationUri)
.OneWay()
.SourceDescribed(#"If(IsFake, 'res:ic_lock_open_white', 'res:ic_info_outline_white')");
Whenever I try to create a new MMDeviceEnumerator I get an error
MMDeviceEnumerator DevEnum = new MMDeviceEnumerator();
gives me
An unhandled exception of type 'System.InvalidCastException' occurred in NAudio.dll
Additional information: Unable to cast object of type 'MMDeviceEnumerator' to type 'NAudio.CoreAudioApi.Interfaces.MMDeviceEnumeratorComObject'.
I'm using VS Community 2015, Naudio 1.7.3, on Windows 7 64 bit. Does anyone have a solution to this? NAudio's Midi API seems to work fine.
I am building a web application using dart with web_ui.
Everything was working fine until i added the web_ui pub, and now, when I am trying to run a build.dart file I get an error:
Uncaught Error: type 'AttributeName' is not a subtype of type 'String' of 'name'.
What does this mean?
From what I understand, this means there is somewhere an instance named 'name' of class 'AttributeName' that is extending 'String' class.
I searched my entire project and there is nowhere a class named 'AttributeName', nowhere an instance of 'name'.
I have the latest Dart editor and SDK:
Dart Editor version 0.4.7_r21658
Dart SDK version 0.4.7.5_r21658
EDIT:
this is my build.dart file:
import 'package:web_ui/component_build.dart';
import 'dart:io';
void main() {
build(new Options().arguments, ['web/menyplattan.html']);
}
Also, i updated all the pubs
This message looks like web_ui is failing a type check.
The similar SO question MarioP links to has a stacktrace showing this message coming from within the web ui library itself.
Do you have an xmlns attribute in your html?
Have a look at this web-ui issue.
AttributeName is defined within the html5lib library. Perhaps web-ui is expecting a newer version of this library but getting an older one. Make sure you've done a pub install. You can also try deleting your packages folder and doing a fresh pub install.
This could be caused by out-of-date packages, but it could also be a bug in web-ui. See if you can get a stacktrace and file a bug report, or post it on the web-ui mailing list.
