Preflight OPTIONS Request

• The error occurs when the browser sends an OPTIONS preflight request before making the actual API request.
• Try adding { withCredentials: true } if authentication is required.

findAllCandidat() { return this.http.get<any[]>(${BASIC_URL}api/cvs/recrutement, { withCredentials: true }); }

Fixed CorsConfig

Update your CorsConfig class to explicitly allow allowedHeaders and allowedMethods:

@Configuration public class CorsConfig {

@Bean
public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurer() {
        @Override
        public void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**")
                    .allowedOrigins("http://localhost:4200")
                    .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
                    .allowedHeaders("*");
        }
    };
}

}
