I am making a modpack on curseforge. I have all the correct versions needed. Backslot is on 1.19.2. The modpack itself is on 1.19.3. Everything is going fine until i try to launch it and get the Error code -1. I also have the correct versions of cloth and fabric api. Here is the crash report:

Mojang changed its versioning scheme for Minecraft. Minor versions can now contain major differences in code, check out their blog post about it for more info.
Many mods will break if they won't get updated to 1.19.3 from 1.19.2

Ok good to know. I would like to put the backslot mod into my modpack because its really cool and fun! Are you planning to update it anytime soon?

yes

Updated to 1.19.3 with a9b7268

Thank you so much! Now i can finally add it to my modpack! its really underrated.
