LuckPerms Error: Node Not Applied - Complete Fix Guide

# LuckPerms Error: Node Not Applied - Complete Fix Guide LuckPerms nodes fail to apply when the permission node is misspelled, context is incorrect, or a higher-priority group denies the permission. Fix it by verifying node spelling with `/lp user permission check `, confirming context syntax matches the server/world name, and checking group weight precedence. This guide shows complete permission debugging. ## Understanding Permission Node Syntax LuckPerms uses a hierarchical permission system where each command requires a specific node. A permission node is a dot-separated string like `essentials.home` or `worldedit.region.set`. **Common Node Failures:** - Typo in node name (`essential.home` vs `essentials.home`) - Missing child nodes (granted `essentials.*` but command needs `essentials.sethome`) - Context mismatch (node set for world "world" but player is in "world_nether") - Negation overriding grants (group has `-essentials.fly` denying flight) - Incorrect capitalization (nodes are case-sensitive in some plugins) ## Step-by-Step Fix ### Step 1: Verify Node is Actually Set Check if the permission exists in the player's or group's permission list: ```bash # Check player permissions /lp user PlayerName permission info # Check if specific node is set /lp user PlayerName permission check essentials.home # Expected output if node exists: # PlayerName has permission essentials.home set to true ``` If the check returns `false` or shows the node doesn't exist, it was never applied. Verify you typed the command correctly. ### Step 2: Apply Permission with Correct Syntax Set the permission using proper LuckPerms syntax: ```bash # Grant permission to user /lp user PlayerName permission set essentials.home true # Grant permission to group /lp group Member permission set essentials.home true # Verify it was set /lp user PlayerName permission check essentials.home ``` **Important:** Some plugins require multiple nodes for a single feature. **Example: EssentialsX /home command requires TWO nodes:** - `essentials.home` - Use the /home command - `essentials.sethome` - Set a home location If you only grant `essentials.home`, players can teleport but cannot set homes. ### Step 3: Check for Permission Negation LuckPerms allows explicit denial using a minus sign. Denied permissions override grants. ```bash # Check for negations /lp user PlayerName permission info | grep "-" # Example output showing denial: # - essentials.fly (set to false) ``` If a permission shows `-node.name`, it's explicitly denied. Remove the negation: ```bash # Remove denied permission /lp user PlayerName permission unset -essentials.fly # Or set it to true to grant instead /lp user PlayerName permission set essentials.fly true ``` ### Step 4: Verify Context Syntax Contexts restrict permissions to specific servers or worlds. Incorrect context syntax causes nodes to not apply. **Context Syntax:** ```bash # World-specific permission /lp user PlayerName permission set essentials.fly true world=world # Server-specific permission (BungeeCord) /lp user PlayerName permission set bungeecord.server.lobby true server=hub # Check what contexts are applied /lp user PlayerName permission info ``` **Common Context Mistakes:** ❌ **WRONG:** `world=World` (capital W doesn't match folder name "world") ✅ **CORRECT:** `world=world` (matches actual world folder name) ❌ **WRONG:** `server=Survival` (doesn't match BungeeCord server name "survival") ✅ **CORRECT:** `server=survival` (lowercase, matches config) **Debug Context Issues:** ```bash # See what world player is currently in /lp user PlayerName meta info # Check server name (BungeeCord) /lp debug ``` The context must exactly match the server/world name. Case-sensitive. ### Step 5: Check Group Inheritance and Weights If a player is in multiple groups, the highest-weight group's permissions take precedence. ```bash # View player's groups /lp user PlayerName parent info # Check group weights /lp listgroups # Example output: # default [weight: 0] # vip [weight: 50] # admin [weight: 100] ``` **How Weights Work:** - Higher weight = higher priority - If `admin` (weight 100) denies a permission, and `vip` (weight 50) grants it, the denial wins - If no weight is set, group has weight 0 **Fix Weight Conflicts:** ```bash # Set group weight /lp group admin setweight 100 # Ensure admin group has higher weight than other groups ``` ### Step 6: Reload Permissions After making changes, force LuckPerms to reload: ```bash # Reload all permissions from storage /lp sync # Or reload specific user (faster) /lp user PlayerName clear ``` Player may need to relog for permissions to apply immediately. ## The MANAfuel Difference The manual debugging above works, but requires understanding LuckPerms node hierarchy, context syntax, and weight precedence. On MANAfuel, Bob AI handles permission analysis. **You:** "Bob, my VIP players can't use /fly even though I granted the permission." **Bob:** "Analyzing PlayerName's permissions. Issue found: VIP group has `essentials.fly` granted (weight 50), but Admin group inherited by PlayerName has `-essentials.fly` denial (weight 100). Admin weight overrides VIP. I've removed the denial from Admin group. PlayerName can now fly." Bob parses the entire permission tree, identifies conflicts, and recommends fixes. He understands that `essentials.*` doesn't always grant every Essentials command due to plugin-specific logic.

Why?** A: The `*` wildcard grants ALL permissions, including potentially dangerous ones. Some plugins explicitly check for specific nodes and ignore wildcards for security. Additionally, if any group has a negation (`-node.name`), it overrides the wildcard grant. **Q: How do I find the correct permission node for a command?** A: Three methods: 1. Plugin documentation (e.g., EssentialsX wiki lists all nodes) 2. Use `/lp verbose on` then execute the command. LuckPerms logs which node was checked 3. Check the plugin's `plugin.yml` file for registered permissions **Q: What's the difference between `essentials.*` and `essentials.**`?** A: - `essentials.*` grants ONE level deep (e.g., `essentials.home`, `essentials.spawn`) - `essentials.**` grants ALL levels deep (e.g., `essentials.item.spawn.stone`) Most plugins only need `*` (one level). Use `**` for comprehensive admin permissions. **Q: Can I copy permissions from one player to another?** A: Yes, by cloning groups: ```bash # Make Player2 inherit same groups as Player1 /lp user Player1 parent info # Note the groups, then: /lp user Player2 parent add ``` For direct permission copy, use LuckPerms web editor (/lp editor) to copy-paste permission nodes. **Q: My permissions work in one world but not another. Why?** A: Context restrictions. If you set: ```bash /lp user Player permission set node.name true world=world ``` The permission ONLY works in "world", not "world_nether" or "world_the_end". Either: 1. Grant without context: `/lp user Player permission set node.name true` 2. Grant for each world: `/lp user Player permission set node.name true world=world_nether` **Q: LuckPerms says "You do not have permission" even though I'm OP. How?** A: LuckPerms overrides OP permissions. Being OP doesn't grant LuckPerms-controlled nodes. Add yourself to an admin group: ```bash # Create admin group if it doesn't exist /lp creategroup admin # Grant all permissions to admin group /lp group admin permission set * true # Add yourself to admin group /lp user YourUsername parent add admin ```
