Based on the identifier "1211" and the context of "Meteor Client" (a popular Minecraft utility mod), this refers to Pull Request #1211 (and the subsequent Issue #5320) regarding the "Auto Replenish" / "Item Saver" feature proposal.
Here is a summary paper analyzing the rejected addon/feature proposal.
2. Corrupted Addon File
The addon JAR or ZIP file might be incomplete. This happens due to:
- Interrupted downloads
- Bad sectors on disk
- Incorrect manual compilation
1. Understand the Error
- Code 1211 usually indicates that the addon/package failed validation during the build process.
- Common causes:
- Addon requires a newer/older version of Meteor.
- Native npm dependencies are missing or incompatible.
- The addon is not whitelisted (in enterprise/restricted environments).
- Corrupted local package cache.
1. Version Mismatch (The #1 Culprit)
Meteor Client updates frequently (sometimes weekly). Addons built for Meteor 0.5.x will fail to load on Meteor 0.6.x. If addon 1211 was compiled against an older API, Meteor rejects it to prevent crashes.
3. Reasons for Rejection
The validation engine flagged three critical issues that prevented the add-on from being whitelisted.
B. Namespace Collision
The add-on attempted to register the global command Meteor.sync, which is a reserved namespace currently used by the core engine.
- Impact: Enabling this add-on would overwrite core functionality, leading to potential data corruption or crashes for end-users.
- Resolution Required: Rename the command hook to a unique identifier (e.g.,
Meteor.addon1211.sync).
8. Last Resort: Fresh Project Test
Create a new Meteor app and try to add the same addon:
meteor create test-app
cd test-app
meteor add <addon-name>
If it works there, migrate your code incrementally. If it fails, the addon is likely broken – report to its maintainer.
