Spring boot & spring security : Error creating bean with name 'securityFilterChain' . When running program - spring-boot

Question

I started implementing JWT webtokens so I can authenticate users. I followed the tutorial given by Dan Vega.
I cannot comprehend what is wrong here.
The error:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

I made an RsaKeyProperties file:

import java.security.interfaces.RSAPublicKey;
#ConfigurationProperties(prefix = "rsa")
public record RsaKeyProperties(RSAPublicKey publicKey, RSAPrivateKey privateKey) {

I enabled the RsaKeyPropertiesFile:
import com.Code.Pakket.management.config.RsaKeyProperties;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
#EnableConfigurationProperties({RsaKeyProperties.class})

public class PakketManagementApplication {

}
}
I use the public and private key inside of the properties file:

Answer 1

The error says
Caused by: java.lang.ClassNotFoundException: org.springframework.security.oauth2.server.resource.web.BearerTokenResolver
Please add spring-boot-starter-oauth2-resource-server dependency in your project.
