LowLevelFatalError - Assertion failed Error

Hi,

I was able to build my project for HTML5. However, I am not able to deploy it onto a server. If I try to run the project locally using HTML5LauncherHelper.exe the project runs without any problem. Once, I move the files into a server (wamp server) project stops working.

Here is the screenshot of the error displayed:

Can anyone help me regarding how to solve this issue?

Just a few things to ask first:

Did you move all files and folders?
Did you change any files’ location?
Sure you added all your maps in Project properties –> Packaging?
As files are being served from compressed versions (.gz), is wamp/apache correctly set to serve these files? If not, browser will not be able to understand the difference of a compressed js file and gibberish.
(Check here caching - How to force Apache to use manually pre-compressed gz file of CSS and JS files? - Stack Overflow)

A solution to try:
You can always use the uncompressed versions from the Binaries\HTML5 folder. Just copy these files to your server:

[PROJECT].data
[PROJECT].data.js
[PROJECT].html
[PROJECT].js
[PROJECT].js.mem
[PROJECT].js.symbols (not needed if you do not know what it is for, UE is already crashed if this file is needed)
Utility.js (if this file is bigger than 54kb, delete it and package html again to get a small one, there is a bug that makes this file bigger, yet not a fatal problem)

Just replace those PROJECT parts with your project name when you are selecting

Then open the .html file in an editor (notepad/textedit is fine) and scroll down to the near-end. You can see a list of files in here. Remove the .gz parts. You’ll see something lik


    // start downloads in parallel, print when done.  
    var promises = 
			'Utility.js.gz',
			'Something.data.js**.gz**',
			'Something.js**.gz**'   
		].map(download);

Also, open the [PROJECT].data.js file (small one, mostly 7kb in size). Remove the .gz from here to (4.10 does not add a .gz here, so if you do not see it, it’s ok).


    var REMOTE_PACKAGE_BASE = 'Something.data**.gz**';

Then refresh your project again. See if it is running ok.
