No such export in a resource

The problem

The console shows «No such export 'X' in resource 'Y'» (or the export returns nil) when calling `exports['Y']:X()`.

The cause

Three typical causes: (1) resource 'Y' isn't started or loaded AFTER the one calling it; (2) the export or resource name is misspelled; (3) the export is registered on the other side (client vs server) from where you call it.

The solution

Check the load order, the exact name and the side (client/server):

-- 1) ORDER in server.cfg: the resource that EXPORTS goes before the one using it.
ensure Y          -- first the one providing the export
ensure my_script  -- then the one calling it

-- 2) EXACT name (case and dash sensitive):
exports['ox_inventory']:AddItem(src, 'water', 1)   -- correct
-- exports['ox-inventory']  <- wrong (dash vs underscore)

-- 3) Right side: a SERVER export doesn't exist on the client.
--    Check whether 'Y' registers that export in client.lua or server.lua.

Step by step

1. 1.Confirm resource 'Y' is in `ensure` and starts WITHOUT errors.
2. 2.Put it BEFORE your script in server.cfg (dependencies first).
3. 3.Check the exact resource and export name (case, dash vs underscore).
4. 4.Make sure you call the export on the right side (client/server).
5. 5.If 'Y' is paid/escrow, check its docs: the author sets the export name.
