md_5.bungee.protocol.EntityEffect 79

[Keaton1188]

Hi there, having this strange issue on our new FTB Builders Paradise Server, it is kicking me with a md_5 protocol Entity Effect error and doesn't let me back in. Not sure if this is pack related to Travertine or the Mod pack.

This is the error from Travertine Console.

Did u find the cause of this?

I can confirm this

@electronicboy is there any Solution for this issue?

[electronicboy]

No, because I've not had the investment to rip apart 100 mod packs to work out what some mod is doing to the packet, or if the behavior causing this is still applicable to "modern" versions of forge or even at all, PaperMC/Waterfall#418

I have the same issue. Right after I died in game, it wouldn't let me reconnect. it says the server is down, but it clearly isn't.

@electronicboy after some research and testing i found that the mod Just Enough IDs is sending the packet,the mod expands the max IDs can be used

Judging from JEID's resource code, it extends the potion effect packets in a non-standard way which breaks Waterfall because of a fix to a Forge 1.8 issue.

I see three options: complain that JEID is non-standard (not really an option), drop the 1.8.9 bugfix (since Minecraft 1.8 is over 6 years old and needs to go away) or flat-out say that JEID is not supported on Waterfall/Travertine and to use Velocity instead (which does not intercept the packet and doesn't have the issue).

@astei it happens when dying too so i don't think it's directly potion related

[electronicboy]

The packet is the one used for potion effects

[Irgendwer01]

isn't there any way to let Travertine ignore this packet?

Well yes, disable entity meta rewriting in the config. If you still have issues then I’d suggest you try using Velocity instead of Travertine. I’m sure that if the config option doesn’t fix it, Velocity won’t have the issue at all
