Setup issue

This is the error i am trying to solve from many hours:
{"message": "An unexpected error occurred: Illegal base64 character: '@'"}
I am getting it on postman because the mvn spring-boot:run is running this on port only not opening it on localhost
The backend is still trying to decode a JWT token in the Authorization header even for public endpoints.

The JwtAuthenticationFilter runs for every request and attempts to parse the Authorization header if present.

If Postman or the browser sends any header (or even an email with @), the filter throws a Base64 decoding error, blocking the login request.

Root cause:
The JwtAuthenticationFilter does not skip public URLs defined in PUBLIC_URLS.
As a result, /api/users/login is incorrectly processed by the JWT filter.

Impact:
Cannot test /login endpoint in Postman.
Prevents new users from logging in or getting a JWT token

Sure AmrElsayyad.

The /api/users/register and /api/users/login endpoints are public URL's and do not require a Bearer token, while all other endpoints, except /logout, require a token to access. The public URLs are functioning correctly as expected.

Illegal base64 character: '@'
it means a request was sent without a valid Bearer Token, and the JwtAuthenticationFilter attempted to decode an invalid Authorization header. This happens even for public endpoints since the filter runs globally. Always ensure you pass a proper Authorization: Bearer <JWT_TOKEN> header for protected endpoints.

Correct workflow will be:
Use Postman (or any API client) to hit:
POST http://localhost:8180/api/users/register
with the required body to register a new user.

Then use the same email and password with:
POST http://localhost:8180/api/auth/login
to obtain a JWT token.

Pass this JWT token as a Bearer Token in the Authorization header for all other API requests.
