Unable to integrate Sentry with Lambda

SDKs

We have a lambda function in Java, no framework we are using.

We are unable to integrate Sentry in lambda.

Below is my SentryConfig.java file

package com.my.mypackage;
import java.io.IOException;
import java.util.Arrays;
import java.util.Properties;
import java.util.Set;
import java.util.TreeSet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.my.exception.MyException;
import com.my.model.PropertyReader;
import io.sentry.Sentry;
import io.sentry.SentryClient;
public class SentryConfig {
	
	private static final Logger LOG = LoggerFactory.getLogger(SentryConfig.class);
	
	private final String propertyFile = "config.properties";
	
	public SentryClient initializeSentry(){
		try {
			Properties prop = new PropertyReader().readPropertyFile(propertyFile);
			String environment = prop.getProperty("environment");
			if (!Utils.isEmpty(environment)) {
				String sentryDns = prop.getProperty("non_prod_sentry_dns");
				if(environment.equals("PROD")) {
					sentryDns = prop.getProperty("prod_sentry_dns");
				}
				LOG.info("Initializing sentry for {} environment.", environment);
				return initializeSentry(environment, sentryDns);
			} else {
				// No need to setup sentry for DEV environment
				LOG.info("Please setup environment property");
				return null;
			}
		} catch (IOException e) {
			throw new MyException(MyConstant.UANBLE_TO_LOAD_CONFIG);
		}
	}
	private SentryClient initializeSentry(String env, String dsn) {
		Sentry.init(dsn);
		SentryClient sc = Sentry.getStoredClient();
		sc.setEnvironment(env);
		return sc;
	}
}

I am invoking Sentry as below

(new SentryConfig()).initializeSentry();
Sentry.getContext().addExtra(“payload”, request.toString());
Sentry.capture(ex);

It working fine when I run it locally but not with lambda.
