To view the error yourself, I’ve continued hosting the HTML5 site at www.JacobBeauseigneur.com/64bit/PortfolioArcade

It seems like FGenericPlatformProcess::LaunchURL is not implemented for HTML5 - UE-10825 has been created for internal tracking - It seems like it should be a quick fix.

I will update this once it has been implemented.

Hi Sephern, This should now be fixed in GitHub master branch.

4

Just commenting that if the fix was/is in the master branch, it didn’t make it into 4.7.2. I’m downloading from source now to test for myself if it is in the master branch.

5

I have tried in both the 4.7.3 source and the master branch source, and the links still are not working, and they are giving me the same error.

6

Hi Sephern,

Is the error log exactly the same? I would expect is to be different as it should be calling a new function. Might be worth confirming you’ve got the commit into your source? The commit to fix the problem was this link text . The commit is in master, so it won’t be in 4.7.3

7

I was wrong, it is a new error. I apologize, that was my mistake. Here’s the error:

That callstack doesn’t really help much, is there any other error information before it?

9

There isn’t. It is a rather large project and I haven’t looked into how to gzip yet, but your internet is probably faster than mine.

It works perfectly when working in editor, and I won’t be at a computer with emscripten, nor do I know exactly how I’d look up any other errors for this from the engine. This iteration may have been packaged in 4.7.2 from the Launcher, but when I get home I will export one with 4.7.3 to grab the error. At home, the error was still giving me this part of the error:

jsStackTrace@http://jacobbeauseigneur.com/64bit/UE4Game.js:853:12 stackTrace@http://jacobbeauseigneur.com/64bit/UE4Game.js:867:21 abort@http://jacobbeauseigneur.com/64bit/UE4Game.js:5089947:24 abort@http://jacobbeauseigneur.com/64bit/UE4Game.js:9533:2

It seems to give less of an error from the server side now than it did for me last night.

I did have it exported from 4.8.0 (master branch) and 4.7.3, and when it didn’t work I deleted out my master branch compiled from the source and went to the 4.7 branch thinking it would work since I believe you made the update in 4.7.2.

When opening the file from my desktop onto Firefox 32-bit in 4.7.3:

Hi Sephern,

Sorry it’s a late reply. Although the fix was done around the 4.7.2 release is not been moved to the 4.7 branch and I wouldn’t expect to be added for any 4.7 release. You’ll have to build from 4.8/master branch to get it.

Thank you so much for the fix! I truly appreciate the time and effort of everyone that helped get this working!
