Dynmap: Spigot 1.13.2 renders nothing with IllegalArgumentException

[mikesbytes]

I can open the web UI but nothing renders. I can see player positions but every time it tries to render chunks, the console spits out the following error

[05:01:52 ERROR]: [dynmap] Exception during render job: org.dynmap.MapManager$CheckWorldTimes@67504b37

I am using the latest spigot build for 1.13.2 with Java 8

I'd like to retract the above comment of mine, and say that this seems to have been an issue with the specific version of spigot I was on. After updating again today, the issue is gone and everything functions normally.

So to reiterate...

• Problem version:
  
  
  
  • CraftBukkit version git-Spigot-bc4adcb-8cd538e (MC: 1.13.2)
  
  
• Fixed version:
  
  
  
  • CraftBukkit version git-Spigot-a1f2566-97b0057 (MC: 1.13.2)
  
  

This is not an issue on Dynmap's end.

Thanks, I suspected it might be a spigot issue. Closing this.

From a fresh install today...

This server is running CraftBukkit version git-Spigot-a1f2566-8cd538e (MC: 1.13.2) (Implementing API version 1.13.2-R0.1-SNAPSHOT)

I am seeing this issue.

[hammypants]

Damn-- I just did a full recompile as a sanity check and I guess my build from even earlier today was bad.

Do either of you on this issue know what was fixed? Should I be expecting Spigot to be breaking this frequently?

I don't know exactly what Spigot fixed, sorry. Just that the latest build is functional.

Should I be expecting Spigot to be breaking this frequently?

If you are using 1.13.2 - Yes. It is still in active development, and not yet listed as the recommended version. In fact, 1.12.2 is still the current recommended one. You'll want to keep an eye on the Spigot website for announcements regarding that.
