BluAge L3 Demo Application start up fails. Go-Live-Deploy-Start application

The issue you're experiencing with the BluAge L3 Demo Application failing to start during the Go-Live-Deploy-Start application phase is likely related to configuration problems or dependency issues. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Check your Redis configuration: Ensure that the Redis server is running and accessible. Verify that the connection details (host, port, password if applicable) are correctly set in your application's configuration files.

2. Verify database configuration: Double-check your database connection settings, including the URL, username, and password. Make sure the database server is running and accessible.

3. Review application properties: Examine your application.properties or application.yml file to ensure all necessary configurations for Redis, database, and other components are correctly set.

4. Check dependencies: Ensure that all required dependencies are present in your project's build file (pom.xml for Maven or build.gradle for Gradle) and that there are no version conflicts.

5. Examine logs: Look for more detailed error messages in the application logs. They might provide additional information about the specific cause of the failure.

6. Validate data sources: Ensure that all required data sources (jics, bluesam, bac, primary) are correctly configured and accessible.

7. Check naming conventions: Verify that the names of your resources (such as databases) match exactly between your configuration files and the actual resources. Sometimes, case sensitivity can cause issues.

8. Verify secrets: If you're using AWS Secrets Manager for database credentials, check that the ARN is correct and that your application has the necessary permissions to access the secrets.

9. Review the SpringBootLauncher.java class: Make sure any recent changes to this class are correct and align with the workshop instructions.

If you've checked all these areas and the issue persists, you may need to reach out to the AWS BluAge L3 workshop support team for further assistance. They can provide more specific guidance based on the workshop's setup and requirements.
