None of the suggested "duplicates" seem to be related to code-completion. |

Can you share the project or at least the file the caused this error? |

I've create a stripped version of one of my projects, where this behavior occurs. You can check it out at https://github.com/nyn3x/vscode-autocomplete-error If you go to the |

It seems this issue #40355 is related. I a little bit investigated it and ran into this crash. I used the following test to reproduce the issue /// <reference path='fourslash.ts'/>
// @esModuleInterop: true
// @moduleResolution: node
// @target: es2015
// @module: esnext
// @Filename: /node_modules/@bar/foo/index.d.ts
//// export = Foo;
//// declare class Foo {}
//// declare namespace Foo {} // class/namespace declaration causes the issue
// @Filename: /node_modules/foo/index.d.ts
//// import * as Foo from "@bar/foo";
//// export = Foo;
// @Filename: /index.ts
//// import Foo from "foo";
//// /**/
goTo.file("/index.ts");
verify.completions({
marker: "",
includes: ["Foo"],
preferences: {
includeCompletionsForModuleExports: true
}
});Error: Debug Failure. Symbol parent was undefined. Flags: ExportDoesNotSupportDefaultModifier|Alias|AliasExcludes|ModuleMember|Classifiable|Transient. Declarations: undefined.

I can confirm I'm having the same problem with TypeScript v.4.0.x in my VSCode. I have to stick to v.3.9.7 for now unless there's a workaround? |
|
Hmm - but that doesn't seem to work for me. I changed in the package.json the typescript to "^3.9.7" and then set the typescript-sdk to the local workspace. But still I get |
Hmm... interesting, 3.9.7 works for me, it doesn't throw that error and the suggestions work. Interestingly, when I tried a fresh project (I use Next.js), there was no error at all with 4.0.2, so I'm suspecting one of the dependencies in my project may be causing that issue... |

maybe - I did upload a sample-project, which shows this error ... It seems that However - why did I include this setting in my project? I guess it was, so I don't get errors when doing |

Steps to Reproduce:
In any *.ts or *.js file, when I try to use auto-completion for eg
consoleby typingconand then pressing[STRG]+[SPACE]I'm not prompted with the expectedconsole. However: once I completed typingconsoleI get suggestions forconsole's members.Looking at the "Log (Extension Host)" I see the following error:
However: for a split second, this seems to work alright - maybe before the internal initialization of some vscode routine complete?
Does this issue occur when all extensions are disabled?: Yes
