如何在 Node Js 中将对象绑定到 Oracle 过程调用？

问题描述

我正在将对象绑定到 oracle 过程，但它抛出错误“njs-012：在参数 2 中遇到无效的绑定数据类型”

这是我的 Oracle 包定义， 所有变量

 create or replace PACKAGE allVariables AS

我从节点 js 应用程序调用了该过程，但它抛出错误：“错误：njs-012：在参数 2 中遇到无效的绑定数据类型”。参数2中的数据类型有什么问题？

const result = await conn.execute("BEGIN calculate_allhealthoutcomes.HealthOutcomeCalculator(:input,:output); END;",{
            input: { dir: oracledb.BIND_IN,val: {
                            PatientAge:35,// USERNAME:"TESTUSER",PatientGender:"M",Height: 155,Weight: 60,// "PATIENTHEIGHT":155,WristCircumference:10,ForearmCircumference:7,WaistSize:33,HipSize:38,ActivityLevel:"HIGH"
                        },type: oracledb.OBJECT
                                // type: oracledb.STRING
            },output: { dir: oracledb.BIND_OUT,type: oracledb.OBJECT }
        },{});

请帮忙，TIA。
