CORs issue when accessing backend from angular frontend

[late mango]

I keep getting cors issues but I am pretty sure I am configuring cors correctly on the backend. Am I missing something

package com.example.demo.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configurationpublic class CorsConfig implements WebMvcConfigurer {
  @Override public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/api/**").allowedOrigins("http://localhost:4200").allowedMethods("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS").allowedHeaders("*").exposedHeaders("Authorization").allowCredentials(true);
  }
}
