Error booting runtime

[ghost]

hi, I try to include an custom identity provider into the transfer sample. however i face errors while booting runtime:

this is my custom identity service:

package org.eclipse.edc.spi.iam;

import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.eclipse.edc.spi.monitor.Monitor;
import org.eclipse.edc.spi.result.Result;

import java.security.KeyStore;
import java.security.PrivateKey;
import java.security.cert.X509Certificate;

public class CustomIdentityService implements IdentityService {

    private final Monitor monitor;
    private final KeyStore keyStore;
    private final String keyAlias;
    private final String keyPassword;
    private final AudienceResolver audienceResolver;

    public CustomIdentityService(Monitor monitor, KeyStore keyStore, String keyAlias, String keyPassword, AudienceResolver audienceResolver) {
        this.monitor = monitor;
        this.keyStore = keyStore;
        this.keyAlias = keyAlias;
        this.keyPassword = keyPassword;
        this.audienceResolver = audienceResolver;
    }

    @Override
    public Result<TokenRepresentation> obtainClientCredentials(TokenParameters parameters) {
        try {
            PrivateKey privateKey = (PrivateKey) keyStore.getKey(keyAlias, keyPassword.toCharArray());
            X509Certificate certificate = (X509Certificate) keyStore.getCertificate(keyAlias);

            String audience = audienceResolver.resolve(parameters.getRemoteMessage());

            String token = createJwtToken(audience, parameters.getRegion(), privateKey, certificate);
            return Result.success(TokenRepresentation.Builder.newInstance().token(token).build());
        } catch (Exception e) {
            monitor.severe("Error obtaining client credentials", e);
            return Result.failure("Error obtaining client credentials: " + e.getMessage());
        }
    }

    @Override
    public Result<ClaimToken> verifyJwtToken(TokenRepresentation tokenRepresentation, VerificationContext context) {
        try {
            String token = tokenRepresentation.getToken();
            X509Certificate certificate = (X509Certificate) keyStore.getCertificate(keyAlias);
            Claims claims = Jwts.parser()
                    .setSigningKey(certificate.getPublicKey())
                    .parseClaimsJws(token)
                    .getBody();

            ClaimToken claimToken = ClaimToken.Builder.newInstance()
                    .claim("audience", claims.getAudience())
                    .claim("region", claims.get("region"))
                    .build();

            return Result.success(claimToken);
        } catch (Exception e) {
            monitor.severe("Error verifying JWT token", e);
            return Result.failure("Error verifying JWT token: " + e.getMessage());
        }
    }

    private String createJwtToken(String audience, String region, PrivateKey privateKey, X509Certificate certificate) {
        long nowMillis = System.currentTimeMillis();
        Date now = new Date(nowMillis);

        return Jwts.builder()
                .setSubject("client-id")
                .setAudience(audience)
                .claim("region", region)
                .setIssuedAt(now)
                .setExpiration(new Date(nowMillis + 3600000))  // Token validity 1 hour
                .signWith(SignatureAlgorithm.RS256, privateKey)
                .compact();
    }
}

can anybody see my mistake? thanks in advance

you need to register the service on the runtime (it is well explained in the basic-02 sample) , you'll also need an AudienceResolver as well

now i have an audience resolver and registered the service on runtime. But now I get this error:
