Are you a mod developer or user on CurseForge, struggling with the "Failed to generate code" error? You're not alone. This issue can be frustrating, but fear not! We've compiled a comprehensive guide to help you understand and troubleshoot this problem.
Understanding the "Failed to generate code" Error
The "Failed to generate code" error typically occurs when CurseForge is unable to process and generate the necessary code for your mod. This could be due to a variety of reasons, ranging from issues with your mod's metadata to problems with CurseForge's servers.
Common Causes and Solutions
Before we dive into troubleshooting, let's explore some common causes and their respective solutions:

- Incorrect or Missing Metadata: Ensure your mod's metadata (like modid, name, version, etc.) is correct and complete. Incorrect or missing metadata can cause CurseForge to fail in generating code.
- Mod Conflicts: If you're using other mods that modify the same game files, they might be causing conflicts. Try disabling other mods temporarily to see if the issue persists.
- Outdated or Incompatible Mods: Ensure your mod is compatible with the game version and other mods you're using. Outdated or incompatible mods can cause various issues, including this error.
- Server Issues: Sometimes, the issue might not be with your mod or setup, but with CurseForge's servers. In such cases, you might need to wait for CurseForge to resolve the issue.
Troubleshooting Steps
Now, let's delve into the troubleshooting process. Follow these steps to help resolve the "Failed to generate code" error:
-
Check your mod's metadata:
- Open your mod's jar file.
- Locate the "mods.toml" file and check if all the metadata fields are correct and complete.
Check for mod conflicts:

- Disable other mods temporarily to see if the issue persists.
- If the issue is resolved, enable mods one by one to identify the conflicting mod.
Update your mod and other mods:
- Ensure your mod and other mods are compatible with the game version and each other.
- Update your mod and other mods to their latest versions.
Contact CurseForge Support:
- If you've checked and ruled out all other possibilities, it might be a server issue. Contact CurseForge support for further assistance.
