通过Node.js mssql插入加密列显示错误

如何解决通过Node.js mssql插入加密列显示错误

表中有2列Always Always Encrypted，我试图使用Node.js将数据插入表中，但显示错误：

操作符类型冲突：varchar与使用（encryption_type ='DETERMINISTIC'，encryption_algorithm_name ='AEAD_AES_256_CBC_HMAC_SHA_256'，column_encryption_key_name ='CEK_Auto1'，column_encryption_key_name_p_DE_database加密的varchar（8000）不兼容

代码：

var Promise = require('bluebird');
var sql = require("mssql");
var config = require("./config.json");

const insertPatient = Promise.promisify(function() {
        const sql_config = config.mssql_config
        
        sql_config.encrypt = true;

        var conn = new sql.ConnectionPool(sql_config);      

        var msg = {SSN:'999-99-0005',FirstName:'Lucy',LastName:'Harrington',BirthDate:'2020-10-21T10:10:21.273'}

        var insertStr = "insert into Patients (SSN,FirstName,LastName,BirthDate) values ( @p_SSN,@p_FirstName,@p_LastName,@p_BirthDate) ;"

        conn.connect().then(function() {
            const ps = new sql.PreparedStatement(conn);
            ps.input('p_SSN',sql.Char(11));
            ps.input('p_FirstName',sql.NVarChar(50));
            ps.input('p_LastName',sql.NVarChar(50));
            ps.input('p_BirthDate',sql.Date);
            
            ps.prepare(insertStr,prepare_err => {
                if (prepare_err != null) {
                    console.log("insertPatient -err on prepare: " + prepare_err);
                }
                ps.execute({p_SSN: msg.SSN,p_FirstName: msg.FirstName,p_LastName: msg.LastName,p_BirthDate: msg.BirthDate },(execute_err,result) => {
                    if (execute_err != null) {
                        console.log("insertPatient - err on execute: " + execute_err);
                    }
                    ps.unprepare(unprepare_err => {
                        if (unprepare_err != null) {
                            console.log("insertPatient - err on unprepare ::" + unprepare_err);
                        }
                    })
                })
            })
        }).catch(err => {
            console.log('Database Connection Failed! The Error is: ' + err);
        })
    })

    insertPatient()
