如何在 Node Js 中将对象绑定到 Oracle 过程调用？

Question

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

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。
