Error: Debug Failure. False expression: Unexpected node. #11933

ghost · 2016-10-29T04:16:20Z

TypeScript Version: nightly (2.1.0-dev.20161028)

I'm not sure what code is causing this issue, as I have a few dozen code files and no particular file seems to be called out in the error.

Error: Debug Failure. False expression: Unexpected node.
Verbose Debug Information: Node 136 was unexpected.

I am going to attempt to isolate the issue by removing code until the issue goes away.

ghost · 2016-10-29T16:14:10Z

Actually, the issue seems to be resolved in (2.1.0-dev.20161029)

ghost · 2016-10-31T05:22:41Z

~~Issue seems to be related to Node 7.~~ Not resolved.

ghost · 2016-10-31T05:28:07Z

Issue seems to be with

import { Component, ViewChild, Input, Output, EventEmitter } from '@angular/core';
import { ModalDirective } from 'ng2-bootstrap';

@Component( {
    selector: 'modal-choose',
    templateUrl: 'templates/modal/choose.html'
} )
export class ModalChooseComponent {
    @ViewChild('chooseModal')
    protected chooseModal: ModalDirective;

    @Output()
    public onChoose = new EventEmitter<string>();

    @Input()
    public title = '';

    @Input()
    public prompt = '';

    @Input()
    public buttons = [] as string[];

    @Input( 'default-button' )

public defaultButton: string|undefined;

    protected dismiss() {
        const { defaultButton } = this;
        if( defaultButton ) {
            this.choose( defaultButton );
        } else {
            this.hide();
        }
    }

    protected choose( button: string ) {
        this.onChoose.next( button );
        this.hide();
    }

    public show() {
        const { chooseModal } = this;
        chooseModal.show();
    }

    public hide() {
        const { chooseModal } = this;
        chooseModal.hide();
    }
}

I can ont get the error to reproduce locally. can you share more context?

@mhegazy Sounds like you need to npm install both dev and production dependencies. My mistake.

mhegazy · 2016-10-31T19:10:32Z

no luck still:

c:\test\11933\r3>node node_modules/typescript/bin/tsc -p client/tsconfig.json

I've repro'd this on 4 different machines now. 2 are Windows 10 x64, 1 is Windows 7 x64, one is Linux x64. Node v6.9.1 and Node v7.

Strate · 2016-11-30T11:11:23Z

Almost same issue with typescript@2.2.0-dev.20161130 and typescript@2.1.1 (rc):

Error: Debug Failure. False expression: Unexpected node.

    at generateClassElementDecorationExpressions (/devel/src/hotfix/megaplan/front/node_modules/typescript/lib/typescript.js:46298:34)

But happens only with ts-loader or awesome-typescript-loader.

UPD.

happens if emitDecoratorMetadata & experimentalDecorators and property has a decorator like

class BLabla {
  @inject private member: Member | null = null;
}

then:

metadata emitted as Object, not as Member (this might be a breaking change!)
Exception described above is raised.

mhegazy · 2016-11-30T18:41:52Z

metadata emitted as Object, not as Member (this might be a breaking change!)

Object is what i expect. union types in general are represented as Object.

Exception described above is raised.

Can you share more context. i can not get this to repro locally:

c:\test>type a.ts
class Member { }

class BLabla {
  @inject private member: Member | null = null;
}

c:\test>tsc --v
Version 2.2.0-dev.20161130

c:\test>tsc a.ts --emitDecoratorMetadata --experimentalDecorators
a.ts(4,4): error TS2304: Cannot find name 'inject'.

@mhegazy @Strate Hi, i get almost same errors in my project and more detail here:

http://stackoverflow.com/questions/40990736/error-debug-failure-false-expression-unexpected-node-when-typescript-upgrade

I think the issue should be caused by typescript@2.1 or awesome-typescript-loader, but I haven't solved it yet.

I get the same errors with typescript@2.2.0-dev.20161206.

ghost · 2016-12-06T16:06:51Z

I never pinpointed the issue, but I was not using awesome-typescript-loader (or webpack), so I do not think that is related.

mhegazy · 2016-12-06T17:28:25Z

A repro project would be appreciated.

sheetalkamat · 2016-12-06T17:56:59Z

@errorx666 I tried repro steps in #11933 (comment) and just like @mhegazy I haven't been able to repro this. Need a repro to be able to look into this. Thanks.

aluanhaddad · 2016-12-07T04:13:20Z

For the related issue, #12684 I was able to repro immediately using the instructions in #12684 (comment)

sheetalkamat · 2016-12-08T23:40:41Z

I am not sure what kind of interactions with the plugins going there in the repro. But if I did below steps I don't repro the issue:

>node tsc --v
Version 2.2.0

>node tsc -p c:\repro\tsissuedemo\src

>echo %ERRORLEVEL%
0

…adata type Fixes #12684 and #11933

@ASHISH060792 this is almost 2 years old issue with some 8 releases in between.

Please file a new issue, and give us some repro steps, or sample project to be able to help you out.
