Can't connect to a server

QFAPI / QSL Version: QFAPI 4.0.0-beta.28 and QSL 3.0.0-beta.29

Description: I tried to join this whitelisted server that supports both 1.19.3 and 1.19.2 clients with the mods that I play and then I get an error message (shown in screenshots). I went through my mods list and found that this only happens when QFAPI / QSL is enabled, as when I have no mods in my instance / folder with just Quilt Loader 0.18.2, I can connect to the server with no issues

This was also transferred from the Quilted Fabric API gituub since I think it is an issue with QSL having a different registry system to match mods whereas Fabric doesn't really care at all

This is issue with you trying to join 1.19.3 server with 1.19.2. Because of experimental content (in this case camel), registries aren't matching required (vanilla) entries. It's pretty much intended behaviour.

[stantios]

But experimental features was not enabled on the server so I don't understand how that works?

[Patbox]

Even if they aren't enabled, they are still registered/present in game's registries (so technically you could place 1.20 blocks with some extra mod/tool and they would be preserved without enabling experimental features)

[stantios]

Oh, I didn't know that. I guess it's this issue can't be resolved due to registries missing on 1.19.2, the server uses ViaVersion with ViaBackwards to allow older clients and newer clients to join so how would that work?

[Patbox]

ViaFabric could mark every vanilla entry as optional (with qsl api), which would allow it to bypass registry sync

[stantios]

The thing is they don't support old versions and adding new features to them as they only support the latest version of each major version like 1.19.4, 1.18.2, 1.17.1 and morr. So someone would probably need to make an addon of some sort to allow ViaFabric to mark every vanilla registry as optional to bypass the registry sync.
