I can not connect to my app client. The following is the code I use:

const AWS = require('aws-sdk');
    // AWS.config.region = 'ap-southeast-2'
    AWS.config.update({ region: 'ap-southeast-2' });
    try {
        var params = {
            AuthFlow: 'ADMIN_NO_SRP_AUTH',
             ClientId: process.env.COGNITO_CLIENT_ID,
            UserPoolId: process.env.COGNITO_USER_POOL_ID,

            AuthParameters: {
                email: "na****@*****.com",
                password: "********",
            }
        };
        console.debug("params: ", params)
//{apiVersion: '2016-04-18'}

        var cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider();

        const res = await cognitoidentityserviceprovider.adminInitiateAuth(params, function (err, data) {
            if (err) {
                console.debug("error adminInitiateAuth. params: ", params);
                console.log("err: ", err);
                
    return { props: { data } }
            } else {

The output is:

err:  ResourceNotFoundException: User pool client ******* does not exist

I am this close to start crying like a baby if this doesnt work
