CurseForge Beta mods error

[RavenProfit 0]

I'm trying to made a custom mod pack for the first time and received an error I don't know how to troubleshoot. The other modpacks I use are working just fine like Valhelsia 3, but I'm not sure what to do here.

 

Any advice would be much appreciated! :)

You have a mod that is not compatible with your Minecraft version.

More cannot be said without seeing the debug.log.
