What could be problem? even though i input the valid username and password it returns the message:"Invalid Username or Password".
THIS IS THE CODE:
const { validationResult } = require("express-validator"); //check for validation errors
const jwt = require("jsonwebtoken"); //used to create and verify JWTs for authentication
const bcrypt = require("bcryptjs"); //used to hash and compare passwords securely
const config = require("../config/auth.config");//import auth.config.js
const db = require("../models/index.js");//database configuration and models from index.js
const refreshTokenModel = require("../models/refreshToken.model");//imports a module
exports.signin = async (req, res) => {
console.log("Signin request received:", req.body);
const errors = validationResult(req);
if (!errors.isEmpty()) {
console.log("Validation errors:", errors.array());
return res.status(400).json({ errors: errors.array() });
}//this uses express-validator to check for validation errors like missing fields or invalid data
try {
const { username, password } = req.body;
const [admins] = await db.query(
"SELECT * FROM admin WHERE username = ?",
[username]
);
console.log("Admin Query Result:", admins);
if (!admins||admins.length === 0) {
console.log("Invalid Username or Password!");
return res.status(401).json({ message: "Invalid Username or Password!" });

Based on the provided code snippet, there are several areas that could potentially cause the issue where the message "Invalid Username or Password" is returned even though you are inputting valid credentials. Here are some possible reasons and suggestions for troubleshooting:

1. Database Query Issue:
- Make sure the database connection is properly configured and established.
- Check if the "admin" table in your database actually contains the username and password you are trying to authenticate against.
- Verify that the query "SELECT * FROM admin WHERE username = ?" is retrieving the correct user based on the provided username.

2. Password Comparison:
- Ensure that the password stored in the database is hashed using the same algorithm (bcrypt) and configuration as the one used during the login process.
- Double-check the hashing and comparison logic to ensure there are no mistakes or discrepancies.
- Verify that the bcrypt.compareSync(password, admin.password) function is correctly comparing the passwords.

3. Validation Errors:
- Confirm that there are no validation errors occurring before the password comparison logic. Check the console.log("Validation errors:", errors.array()) output to see if there are any issues with the input data.

4. Debugging:
- Add more console.log statements throughout the code to track the flow of execution and see the values of variables (e.g., username, password, admins, isPasswordValid) at different stages.
- Log the actual error message when an error occurs to get more insights into what might be going wrong.

5. Token Generation:
- Check if the JWT tokens (access token and refresh token) are being generated and returned correctly after successful authentication.
- Ensure that the tokens are being stored and managed properly in the database.

6. Error Handling:
- Review the error handling mechanisms in place and make sure that any potential errors are being caught and reported correctly.
- Check the error messages in the console logs to identify any specific errors that might be occurring during the authentication process.

By carefully examining these aspects of your code and potentially adding more detailed logging, you should be able to pinpoint the exact cause of the "Invalid Username or Password" message and resolve the issue.

i check all the possible issue and fixed it but it still shows the message "Invalid Username or Password"

If you have already checked and addressed the potential issues mentioned earlier and are still encountering the "Invalid Username or Password" message, here are a few additional steps you can take to further troubleshoot and identify the root cause of the problem:

1. Database Query Verification:
- Manually verify the data in your database to ensure that the username and password are correctly stored and match what you are inputting during the login process.
- Test the SQL query "SELECT * FROM admin WHERE username = ?" directly in your database management tool to see if it returns the expected results.

2. Logging and Debugging:
- Add more detailed logging statements throughout the signin function to trace the flow of execution and inspect the values of variables at critical points.
- Log the SQL queries being executed and the results obtained from the database to verify that the correct data is being retrieved.
- Check if there are any unexpected modifications happening to the username or password values before they are used in the comparison logic.

3. Error Handling and Reporting:
- Ensure that error messages are being logged accurately and comprehensively. Look for any specific error messages or exceptions that might provide more insight into the issue.
- Consider implementing additional error handling mechanisms to catch and report any unexpected errors during the login process.

4. Environment Configuration:
- Verify that the environment variables and configuration settings (such as JWT secret, expiration times, database connection details) are correctly set and consistent across your application.

5. Code Review and Refactoring:
- Review the entire signin function and related code to identify any potential logical errors, typos, or missing pieces that could be causing the authentication failure.
- Consider refactoring the code for better readability and maintainability, which may help in identifying and resolving the issue.

6. Testing in Isolation:
- Try isolating the authentication logic and testing it independently from the rest of your application to focus specifically on the login functionality.
- Use tools like Postman or curl to directly test the authentication endpoints with known valid credentials and observe the response.

By systematically going through these steps and thoroughly examining your code and data flow, you should be able to pinpoint the exact reason why the "Invalid Username or Password" message is persisting and take appropriate actions to rectify the issue.
