I always receive the exception: Cannot read properties of null (reading 'getElementsByTagName')
I'm using the WebGLInput script in my input field (it is a TMP_InputField), and when I test it in my WebGL build, just when I put the focus on the input textbox, the execution is frozen and I receive these error logs in the Chrome console:

My input field configuration in Unity
Unity version used
Unity 2020.3.0f1
Thanks in advance! :)
@sandrade-dcl If you have recently updated your Unity from 2019 it may be the same problem. In my case, I solved the issue by changing the following part of the html template.
Before the change
<div id="unityContainer">
After the change
<div id="unity-container">
Hope this helps.

Hey @jmpy, thanks for the workaround! I will try it! :)
error here:
first there is a call to the method of container, and then a check for null
container.getElementsByTagName('canvas')[0] replace with document.getElementsByTagName('canvas')[0]

Where can change it? I'm happen this same issue

Where can you find <div id="unityContainer">? I don't have this in my index.html..
Finally I change the WebGLInput script, not on the webgl template
You can find something like that on the script but th elif and else is set by commend, just delete the commend symbol
Also see your webgl template canvasid is that same as the script
to this
Hope this help

It worked!! Thanks @jmpy 😄

Yeah, after what @jmpy told me about the name of the div name, I looked for where in the code it was being used and I finally reached to the same solution that you suggest :) In my case I always use the name gameContainer for this div.
It is definitively happening because of the name of the main div container... In my case, as I'm always using the name gameContainer for this div, I had to modify the WebGLInput code in order to set ALWAYS this name into WebGLInput.CanvasId and not others depending on the Unity version.
In my case I replaced this:
static WebGLInput()
{
#if UNITY_2020_1_OR_NEWER
WebGLInput.CanvasId = "unity-container";
#elif UNITY_2019_1_OR_NEWER
WebGLInput.CanvasId = "unityContainer";
#else
WebGLInput.CanvasId = "gameContainer";
#endif
WebGLInputPlugin.WebGLInputInit();
}
by this:
static WebGLInput()
{
WebGLInput.CanvasId = "gameContainer";
WebGLInputPlugin.WebGLInputInit();
}
And it worked!

container.getElementsByTagName('canvas')[0]replace withdocument.getElementsByTagName('canvas')[0]
That solved my problem thx. I am using 2021.3.15f1. For the one who couldn't find the file, it is "webgl-build.framework.js". Which is one of the four files in your Build folder.

This should be referenced in how to install the WebGLInput because my god, I just spent 1 hour looking for this
