Running jest leads to "TypeError: Path must be a string"

[mknet]

My test file

let loader = require("@std/esm")(module, { cjs: true, esm: "js" });
const RenderStreamFactory = loader("./RenderStreamFactory.js").default;

let renderStreamFactory = new RenderStreamFactory();

test('adds 1 + 2 to equal 3', () => {
    expect(renderStreamFactory).toBeNull();
  });

When im invoking jest vom the CLI I get

FAIL  src/RenderStreamFactory.test.js
  ● Test suite failed to run

    TypeError: Path must be a string. Received undefined
      
      at assertPath (path.js:28:11)
      at Object.relative (path.js:1268:5)

If I'm using the loader config in another context without Jest it works fine.
Using version 0.11.3 of @std/ESM

Thanks for your help

Hi @mknet!

Could you create a simple repro repo? I've fixed a similar issue before.

[mknet]

Hey @jdalton,

yeah, I noticed the other issue but since I got another error back I created a separate issue.

I created a repro repo with a simple example. I hope you get the same result.

Thanks @mknet!

I can't repro with jest v21.2.1

Maybe you need to clear your node_modules folder.

Oh boy, yeah, the global installation of jest was outdated. Sorry to bother you and thanks for your help.
