this.payloadHandler.handlePayload is not a function

Description of the problem

When loading a .obj file with OBJLoader2Parallel, an uncaught TypeError is thrown.

Uncaught TypeError: this.payloadHandler.handlePayload is not a function
    processMessage WorkerRunner.js:156
    scopedRunner WorkerRunner.js:137

The environment is created by create-react-app’s dev command (no minificaton) but I suspect it would appear in the prod build as well. I believe this is directly related to https://github.com/mrdoob/three.js/pull/18356. Perhaps the issue wasn’t fully fixed despite my telling @kaisalmen that it was.

Three.js version

• r117.1 (I’m locked to this currently)
• presumably latest as well since changelogs don’t reflect anything that would impact this but I will verify if I get time.
• webpack@4.42.0
• react-scripts@3.4.1

Browser

• All of them
• Chrome
• Firefox
• Internet Explorer

OS

• All of them
• Windows
• macOS
• Linux
• Android
• iOS

shall we close this and re-open if it is re-observed

👍

As far as I can tell the model is in fact loaded fine even with the error present. If some upcoming changes are in fact deprecating this code then I can simply swallow the error until then and hopefully get off of r117

The model was loaded every time. Honestly, I don’t really understand why the error shows up in some cases. If you observe it beyond R117 and Chromium based browser 85+, please let me know.
