Can't build to WebGL

Hey I've been trying to make a WebGL build but it doesnt work either with brotli or gzip, Im always getting this error:

Well if looks like it can't find your java path to compile with but let's see what someone that does many more compiles than I do say.

Are you trying to use this new Local Cache feature for fast platform switching? I'm interesting in trying that too.

 

I did not know about any new Local Cache feature... I guess you are talking about this:

• Editor: Option to run Cache Server locally for quick platform switching

Sounds interesting I want to try that ...

Going back to the topic no Im not using that so thats not the problem

 

Well, I am about to switch to WebGL and try & build. I just built to Android using IL2CPP so it should work I think. Then I will try Windows UWP & I should be set I hope & I'll find out if that Server Cache for fast platform switching works.

Message truncated like you ran out of RAM. How much RAM you have? Try closing any browser sessions, outlook, and other unneeded programs especially when compiling to WebGL I've found.

 

I just did a quick search and yes I found a couple of .h files from GameAnalytics, so do you think thats the problem? I will try to make a build without that anyways.

 

Nothing was selected for those files so I tried deleting them and making a build using brotli compression and I got this error:

Im gonna try again with gzip

 

No errors with gzip but the build doesnt run automatically when finish so I tried running it with firefox and after the unity logo loading screen I get a black screen and a lot of these warnings

"warning: 2 FS.syncfs operations in flight at once, probably just doing extra work1:1:112384"

 

I'm trying to build to WebGL, but most of them fails when the build button works (sometimes the build button just doesn't work).
It happens even with a fresh project.

The error:
Exception: Failed building WebGL Player.

Edited:
Now using a script to build, it does works, but the build button doesn't do anything but closing the build options window.
