Crash bug: Nodes without symbols

[ejuda]

Search terms

node, symbol, property, any

Expected Behavior

It looks like in the following scenario tsc produces a node without a symbol for Source.SomeClass.someProp ([see AST viewer]):

index.d.ts

declare const m: {
    SomeClass: any,
}

export type SomeType = typeof m.SomeClass.someProp;

Type checker in TypeScript playground ([see here]) can correctly deduce the type of SomeType to be any. I'm open to discussion about what TypeDoc should do in this situation, but I think that it at least should not crash.

Actual Behavior

TypeDoc fails to generate documentation due to the following error:

Steps to reproduce the bug

1. Clone the reproduction repository.
2. npm ci
3. npm run docs
4. The Expected a symbol for node with kind FirstNode error should appear.

Environment

• Typedoc version: 0.21.5
• TypeScript version: 4.3.5
