I think 1.4.2b targets 1.19, not 1.19.1 or 1.19.2. Check your Minecraft version.

The server loads the mod fine, mhh weird. But I think this is maybe the case.

Yes the server loads fine because of the mixin ChatHudMixin is in client section of bedrockify.mixins.json:line14, not for server. Plus, there are no other changes in 1.19.1/2 and 1.19.
This means that 1.4.2b can be used with 1.19.2 server without any problem.

Hi! In fact 1.4.2b only targets minecraft 1.19 as it is a backport of a fix on newer versions requested in #174. For 1.19.1/2 the latest version is 1.4.2. I'll update the curseforge/modrinth package name to make sure there is no confusion!

@juancarloscp52 Can you change the "default download" for 1.19? It still references the 1.4.2b not 1.4.2. I fell into this pitfall as well.

Sadly curseforge does not allow to change the default download :(
