What happened?

I am developing a mod for fabric 1.20.1, and integrated the REI API Fabric and Fabric as listed on the description page of this feed. When I try to Data Regen or launch the client, I get this error:

cannot access class_8786class file for net.minecraft.class_8786 not found

It seems there is a referenced minecraft element that no longer exists in the fabric api. I am using the fabric_version=0.86.1+1.20.1 with REI API 13.0.654. Would be helpful if clarification on any compatibility issues I may need to take into consideration.

What mod loaders are you seeing the problem on?

Fabric

What do you think this bug is of?

• Visual
• Recipe Lookup
• Cheat Mode
• Plugin Integration / JEI Plugin Compatibility
• Others

Resolved the Issue. Was not aware that Minecraft and Fabric have an update to 1.20.2. Rolled back to v12.0.648 w/ Fabric v0.88.1+1.20.1. Mod works perfectly.
