node loses the class name from the stack trace when setting --enable-source-maps and the error is thrown in a static method.

Platform

Linux me 6.2.0-33-generic #33~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7 10:33:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

What steps will reproduce the bug?

Compile this code with TypeScript compiler - tsc - and then run compiled file with --enable-source-maps option:

class MyClass {
  static staticMethod() {
    throw new Error('Error in static method');
  }
}

MyClass.staticMethod();

What is the expected behavior? Why is that the expected behavior?

If you run the same code without --enable-source-maps option, the stack trace will be correct:

Error: Error in static method
    at MyClass.staticMethod

What do you see instead?

Error: Error in static method
    at Function.staticMethod

Not sure if this is a NodeJS bug. Perhaps the culprit is the TypeScript compiler.

What does your tsconfig look like? I assume it has source maps turned on?

[KostyaTretyak]

@benjamingr, yes:

{
  "compilerOptions": {
    "outDir": "dist",
    "rootDir": "src",
    "baseUrl": "./",
    "module": "nodenext",
    "moduleResolution": "nodenext",
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true,
    "composite": true,
    "noImplicitOverride": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "noImplicitReturns": true,
    "skipLibCheck": true,
    "target": "es2022",
    "strictPropertyInitialization": false,

}

Is staticMethod present in the source map?

[KostyaTretyak]

@bnoordhuis, this is sourcemap:

{"version":3,"file":"tmp.js","sourceRoot":"","sources":["../src/tmp.ts"],"names":[],"mappings":"AAAA,MAAM,OAAO;IACX,MAAM,CAAC,YAAY;QACjB,MAAM,IAAI,KAAK,CAAC,wBAAwB,CAAC,CAAC;IAC5C,CAAC;CACF;AAED,OAAO,CAAC,YAAY,EAAE,CAAC"}

Where tmp.ts - this is source code file.

[bnoordhuis]

Right, it's missing from the names array. Not a node bug IOW.
