Hello, I'm new to the forum so please guide me instead of attacking.

I'm a frequent Hypixel player, a server exclusively played on 1.8.9 - and I want to create a mod for it.

Not asking help for that forge version, but I do want to know whether I can just develop my mod against the latest 1.21 API and it would work on 1.8.9? am I forced to use the 1.8.9 API?

Merged your questions, you didn't really need to make 2 posts, considering they are the exact same question with 2 different subject lines.

You need to use the forge version for the MC version you wish to mod. There are so many differences between versions in the Minecraft codebase, especially at certain points, that Forge had to make compatibility breaking changes to keep up.

For some odd reason it created a second post after I just edited the title...

Anyway, thank you for the info!

      Thanks, I've now installed a slightly newer version and the server is at least starting up now.

      The crash points to moonlight lib - try other builds or make a test without this mod and the mods requiring it

      Do you have shaders enabled? There is an issue with the mod simpleclouds - remove this mod or disable shaders, if enabled

      Maybe you need to create file in assets/<modid>/items/<itemname>.json with content like this:   { "model": { "type": "minecraft:model", "model": "modname:item/itemname" } }
