the error log includes:

com.erp.controller.AuthController.login(AuthController.java:32)

try debugging the AuthController#login method

and when I say debugging, I mean stepping through with a debugger

[runic wind]

It looks like you are having issues with debugging or issues that can be solved using a debugger.
Check out this article on dev.java to see how debugging works and how to use a debugger.
This Stack Overflow question and its answers also explain debugging in general.

These links describe how to use the debugger in some IDEs:
• Debugging in IntelliJ
• Debugging in Eclipse

[golden aspen]

basically it seems like that method considers the credentials to be invalid

Can you show that method?

        String token = jwtService.generateToken(usuario);

        return ResponseEntity.ok(new LoginResponseDTO(token, "Bearer", usuario.getId(), usuario.getNome(), usuario.getLogin()));
    } catch (Exception e) {
        System.out.println("ERRO NO LOGIN: " + e.getClass().getSimpleName());
        System.out.println("Mensagem: " + e.getMessage());
        e.printStackTrace();
        throw e;
    }
}

}

All the code

What exactly handles the actual authentication? Getting the user, checking the password, etc

[void lotus]

The authentication flow is managed by Spring Security through the DaoAuthenticationProvider, which uses my UserDetailsServiceImpl to load the user from the database and the BCryptPasswordEncoder to validate the password.

Could this error be happening because I'm typing "password: admin" in Swagger, and the code is already encrypted, causing the encrypted password to be encrypted again?

[golden aspen]

idk, I didn't see that part of your code

I'm not opening a rar file on my phone to navigate through code on it lol

[golden aspen]

Passwords shouldn't be encrypted (except during transmission which should be handled by TLS), passwords should be hashed

and then you can use the corresponding APIs to check the password against the hash

With Spring, that's passwordEncoder.matches(passwordFromUser, hashedPassword)

The stack trace mentions

org.springframework.security.authentication.dao.AbstractUserDetailsAuthenticationProvider.authenticate(AbstractUserDetailsAuthenticationProvider.java:141)
Do you have a UsserDetailService?
