    Hi,

    I have tried a sample webgl build to make it run in my mobile device. I hosted the build file locally. However, when I checked the URL, the below error pops up.

    The following tools have been used:

    1. Chrome Version 84.0.4147.105. Didnt work
    2. Firefox version 79.0
    3. Wamp 3.2.2.2
    4. Unity 2019.4.4f1
    5. Compression used: Gzip and uncompressed (both didn't work)
    6. Autographics API and webgl 2.0 both didn't work
    7. Sample build link.

    I searched some forums and they all are not exactly pointing to the mentioned error. I tried adding web.config file for IIS servers as stated in the Unity web deployment manual page and this answer.

    Any idea as to why this is happening?

    Looking at the build, I am able to reproduce the problem, and the issue is that in file UnityLoader.js the function named "UnityLoader.buildCompatibilityCheck" is missing. If I manually add that function in (e.g. by copying it from UnityLoader.compatibilityCheck), the page loads up and I see a 3D model of a chair.

    Now, as for why that function would be missing in 2019.4.4f1, I am not sure. Can you try updating to 2019.4.12f1 and see if the issue still persists there?

    I currently have Unity 2019.4.1f1 and 2019.4.12f1 installed on my computer, and in the files

    C:\Program Files\Unity\Hub\Editor\2019.4.1f1\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\UnityLoader.js
    C:\Program Files\Unity\Hub\Editor\2019.4.12f1\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\UnityLoader.js

    the function "UnityLoader.buildCompatibilityCheck" are present and correct. So try updating to 2019.4.12f1? I am not sure of 2019.4.4f1 would have had some regression that got fixed later.

    Thank you for your reply. I upgraded the project to 2019.4.10f1 LTS and unchecked the compression. Now it works fine.
