STLLoader Giving "errorRangeError: Invalid typed array length: 17576829549" Reading Wrong Number of Faces

I’ve got an STL file with 4811 faces but STLLoader.js is detecting 1818587680 faces. It says 1818587680 faces no matter which STL file I choose.

I see in STLLoader.js, it detects the file is in binary format and it looks at offset 80 here:

  function parseBinary(data) {
      var reader = new DataView(data);
      var faces = reader.getUint32(80, true);

I’m using three and STLLoader in React. I’m importing the modules STLLoader needs using:

import {
  BufferAttribute,
  BufferGeometry,
  FileLoader,
  Float32BufferAttribute,
  Loader,
  LoaderUtils,
  Vector3
} from "three";

I installed three using “yarn add three”
