Uncaught TypeError: e is undefined.

What is wrong?

When i try to run my code, GPU.js gives the following error:

Uncaught TypeError: e is undefined
    getType file:///myproject/thirdparty/gpu.js:14
    getType file:///myproject/thirdparty/gpu.js:14
    traceFunctionAST file:///myproject/thirdparty/gpu.js:14

    n file:///myproject/thirdparty/gpu.js:14

Where does it happen?

In GPU.js when trying to run the following code (that works perfectly in normal JS):

const gpu = new GPU();
const veryCoolFunction = gpu.createKernel(function (m, mLength) {

How do we replicate the issue?

Run the code.

How important is this (1-5)?

Browser: Firefox 94.0.1 64-bit (latest); GPU: Geforce MX330 For me it's important 5 because it seems to be a critical bug with GPU.js, not with my code.
