TypeError: e.getAction is not a function

如果单独一行一个db.collection(table).getTemp()不会报错，但下面这种写在for循环里面写法不支持吗，会报错

                const task = []  
                const searchFields = [{  
                    table: 'goods',  
                    mainField: 'goods',  
                    viceField: 'name'  
                }, {  
                    table: 'address_company',  
                    mainField: 'address_company',  
                    viceField: 'name'  
                }]  
                for (let i = 0; i < 3; i++) {  
                    task.push(db.collection(searchFields[i].table).getTemp())  
                }  

                const dataList = await db.multiSend(task).get()
