(Fixed) Blocker - frequent UEFN crashes: "Failed to connect to beacon", "Network Disconnected", "Verse Language Server Crashed"

[Fresnella]

Update - problen solved:

AndrewScheidecker and I figured out what caused this project to crash - it was a mistake I made in my script. I had accidentally used OnBegin twice in the same script. Andrew was able to reproduce the crash by including two overrides of the same function in a class.

I think this beacon thing is something other people have run into, and it’s being worked on. Yesterday and today I’ve been having that problem, and maybe some other issues too. Currently UEFN is crashing every few minutes, so it’s basically unusable for me. I guess it’s time for me to take a break for a day or two and hope things get straightened out. Thanks for listening!

Update 9/14: UEFN is still crashing every few minutes for me today. Does anyone have troubleshooting suggestions? It happens when I try to play or refresh my game, and most recently when I tried to click Create/Open new project from the toolbar. That time I had been working in a new empty project for a few minutes, because I thought maybe my old project was the problem.

Also I got this warning in VSCode: The Verse Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted."

Maybe the thing last night about my script not running could have been user error with the script, but the crashes seem unrelated to the script. I’ve sent two crash reports.

9/13
UEFN has been crashing intermittently tonight, and now it seems I can’t get things working again at all. First, my Verse script stops running, even though the game does start on Play and the functions that I’m running using the device’s details panels work. I don’t think the script is the problem because sometimes the same script works fine. Then I try refreshing and re playing over and over until eventually I get a Network Connection Lost screen. Also sometimes when I press Play, Fortnite starts up but I’m stuck on a screen that says something like “Loading your editor”. I don’t remember exactly what it says but it’s a peachy pink screen that normally pops up for a few seconds and goes away, but instead it stays there forever.

A few times I was able to get things working again by closing UEFN and the gameplay window, and reopening.

I’m going to take a break and try again tomorrow, things will probably be better.

Here’s a screenshot of my recent output log. I’m also attaching a text file.

Hi! Thanks for reporting this. I’ve pulled all the appropriate logs and passed them to the verse team to look into!

[AndrewScheidecker]

Hi, if you’re willing to share your Verse code that is causing the Verse Language Server to crash in VS Code, that would be helpful to narrow down the problem.

Thank you! Looking back at my script it looks like I accidentally included two OnBegins, so this may be a factor, oops! I’m new to programming.

[Fresnella]

Hello, thanks for the response! Oh wow, looking at that old script I’m seeing that I have an extra OnBegin at the end of the script!! Do you think that’s the problem? I don’t remember when I made that mistake. I guess I chopped the script up and re assembled it a lot and this slipped through. I’m also not positive this is the most recent version of the script, it’s something I copied and pasted into a Google Doc at some point. I don’t know how to access the actual workspace in VSCode because I can’t open the UEFN project.

Pretty sure this is an old version of the script though. I don’t know exactly what the script looked like at the moment when I got the VSCode issue.

[AndrewScheidecker]

I’ve reproduced the crash by including two overrides of the same function in a class. Thanks for the info!

[Fresnella]

Good to know! Thanks for reminding me to look back at the script.
