i been watching, reading tutorials to make sure that i build the API and the connection code right and reading other people that have the same problem and doing what they did none of this fixed my problem.
this is my node.js code:
var postData = req.body; // get post params
var userId = uid.v4();
const userExistQuery = 'SELECT email, first_name, last_name FROM User WHERE email = @email AND category = @category AND password = @password';
if(postData.category.valueOf() == new String("Seller").valueOf()){
connection.request()
.input('email', sql.VarChar(45), postData.email)
.input('password', sql.VarChar(45), postData.password)
.input('category', sql.VarChar(45), postData.category)
.query(userExistQuery)
.then((recordSet)=>{
if(recordSet.rowsAffected == 1){
res.json("Already registered as Seller.");
}else{
var streetNum = postData.streetNum;
var buildingNum = postData.buildingNum;
var apartmentNum = postData.apartmentNum;
var town = postData.town;
var governance = postData.governance;
var floorNum = postData.floorNum;
var poBox = postData.poBox;
var zipCode = postData.zipCode;
var creditInfo = postData.creditInfo;
const addSellerQuery =
'INSERT INTO Seller(seller_id, street#, building#, apartment#, town, governance, floor#, P.O_box, zip_code, credit_info, first_name, last_name, email, password, phone_number ,category) VALUES(@sellerId,@streetNum,@buildingNum,@apartmentNum,@town,@governance,@floorNum,@poBox,@zipCode,@creditInfo,@firstName,@lastName,@email,@password, @phoneNumber, @category)';
connection.request()
.input('sellerId', sql.VarChar(45), userId)
.input('streetNum', sql.VarChar(45), postData.streetNum)
.input('buildingNum', sql.VarChar(45), postData.buildingNum)
.input('apartmentNum', sql.VarChar(45), postData.apartmentNum)
.input('town', sql.VarChar(45), postData.town)
.input('governance', sql.VarChar(45), postData.governance)
.input('floorNum', sql.VarChar(45), postData.floorNum)
.input('poBox', sql.VarChar(45), postData.poBox)
.input('zipCode', sql.VarChar(45), postData.zipCode)
.input('creditInfo', sql.VarChar(45), postData.creditInfo)
.input('firstName', sql.VarChar(45), postData.firstName)
.input('lastName', sql.VarChar(45), postData.lastName)
.input('email', sql.VarChar(45), postData.email)
.input('password', sql.VarChar(45), postData.password)
.input('phoneNumber', sql.VarChar(45), postData.phoneNumber)
.input('category', sql.VarChar(45), postData.category)
.query(addSellerQuery)
.then((recordAdded)=>{
if(recordAdded.rowsAffected == 1){
res.json(dataPost.firstName + "Registered as Seller.");
}else{
res.json(dataPost.firstName + "failed to register as Seller.");
and this is my retrofit code:
public static Retrofit getRetrofit() {
if (retrofit == null) {
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.connectTimeout(120, TimeUnit.SECONDS)
.readTimeout(120, TimeUnit.SECONDS)
.writeTimeout(120, TimeUnit.SECONDS)
.build();
retrofit = new Retrofit.Builder()
.baseUrl("http://10.0.2.2:1433/")
.client(okHttpClient)
.addConverterFactory(ScalarsConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
return retrofit;
this code how i get the data from the api:
compositeSubs.add(myAPI.buyerSignUp(buyer.getEmail(), buyer.getName().split(" ")[0]
, buyer.getName().split(" ")[1], buyer.getPassword(), buyer.bringType(), buyer.getPhoneNumber())
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(s -> { // onNext method
Log.d(TAG, "onPreExecute get data from api");
((AuthListener) callBack).onSignUp(s, compositeSubs, false);
Log.d(TAG, "onPreExecute after get data from api");
}, throwable -> { // onError method
Log.d(TAG, "onPreExecute getting api error");
throwable.printStackTrace();
}, () -> { // onComplete method
Log.d(TAG, "onPreExecute after getting data from api");
Handler handler = new Handler(Looper.getMainLooper());
handler.post(() -> {
if (progressDialog.isShowing())
progressDialog.dismiss();
Log.d(TAG, "completed");
i expect to see the new buyer is added to the buyer table in my database but this Exception prevent from adding the new buyer.
