Question [SOLVED] WebGL Build Error - "Unable to parse Build/[File Name].framework.js.br"

THIS POST HAS BEEN SOLVED - FEEL FREE TO DELETE THIS THREAD

Since last October I've been having issues with building WebGL files across several different versions of Unity. At first, I was running into an error where I could only build a functional WebGL build if I created a Development Build. Now even that workaround won't function. I haven't built a usable WebGL build in months, despite hours of online troubleshooting and retrying. I was hoping somebody here might be willing to help me out.

My current version is Unity 2021.1.4f1.

My newest build gave me an error message, shown below (my file is named "WebGL v1"):


I also took a look in Chrome's developer tools console to investigate the error, shown below:


Here are all of my build settings for WebGL:





As for the project, it's a very simple platformer without any special plugins or packages in use. If you have any more questions about my build settings, my setup, or anything else, please let me know!

Thanks for taking the time to help

 

I solved the issue by changing the Compression Format to "Disabled"

 

I'm having the same problem. Can you let me know where to find the option to change the Compression Format?

 

that is in player settings

 

for anyone having trouble finding the setting

 

You still should not have to disable compression, that makes web files WAY too big. I am having the same problem, so I'll update if I find a solution that allows compression.

 

If there is a same setting, then an error occurs

 

I have the same problem.
And I found out that if I create a 3D project, I don't have this error.

 

Changing the compression to gzip under Publising Settings -> Compression Format solved this problem for me. Found solution HERE.

No good -- this didn't fix it for me in unity 2020.3. The only thing that works is actually disabling compression -- neither format works on dreamhost.

 

I was using 2021.x
Sucks that you have to disable compresw. I imagine that slows down the initial load time.

 

Maybe it’s a dreamhost thing? But yeah, WebGL has always been very slow for us.

 

Using 'zip' compression is working fine for me (2022.1) on itch.io - thanks for this solution.

 

Compression Format seems to be set to "Brotli" by default. Changing to disable worked for me. But changing the format to "Gzip" also worked. I am using a .zip file to upload to Itch.

 

GZIP works.

Thank you and have a good one

 

Hello everyone.

I had the same problem, but the solution I used was to enable Decompression Fallback over Publishing Settings.



Like in this video:

 

Don't know how, but changing the compression format to disabled worked for me.

 

That means your compression is not supported by the target web server (they havent setup their headers etc correctly to handle brotli/gzip)

You can get around this by checking "decompression fallback", rather than selecting no compression.

 

It worked. Thank you!

 

You are a life saver! Thank you for your time to post your solution! ^^

 

This thread is like watching a lamp catch flies...

Y'all do know that disabling compression doesn't fix the fact that your server is misconfigured to handle gzip/brotli right?

 

the compression disabling fixed it thanks!

 

I ran into the same problem now and done some stackoverflows and research on the forums. The error I am getting is :

Unable to parse Build/PROJECTNAME.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.

Unity Version : 2022.2.0f1

In the publish settings settings I have tried all 3 compression formats Brotli, gzip and none. With toggling decompression fallback on/off. I also enabled Developer Build. Nothing I try works

I am trying to get working in github pages. I also found a link on the unity docs where I created web.config files in the build folder and also uploaded that to github pages, nothing works.

I tried it locally by running python -m http.server, that also does not work because it needs an http(s) server for some reason.

Is there anything else I can try please, I dont want to create a new ticket so I am hoping somebody does pick this up...

 

Thanks, this work
