cannot recognize emmy field

I have defined an emmy class role:

---@class role
---@field equipment_mgr equipment_mgr

an emmy class equipment_mgr:

---@class equipment_mgr
local data = {
        role = role, ---@type role
        equipment = orm_equipment, ---@type table<integer, db.Equipment>
}

then add some method to equipment_mgr:

---@type equipment_mgr
local mt = {}
mt.__index = mt

---@return db.Equipment
function mt:get_equipment(uid)
    return self.equipment[uid]
end

Lua Diagnostics cannot recognize the method get_equipment:

while other extension can

Comece reproduzindo a classe Lua, o campo, a metatabela e o método get_equipment mostrados no Lua Diagnostics. Compare o reconhecimento do método com o da outra extensão mencionada; considera-se concluído quando o Lua Diagnostics reconhecer get_equipment em equipment_mgr sem o diagnóstico reportado.
