Fix NoSuchBeanDefinitionException

✅ Solution

NoSuchBeanDefinitionException usually arises when a required component or bean is missing from the Spring application context, often due to a failed OSGi bundle activation or incomplete migration. Resolve this by ensuring all necessary bundles are active and properly wired; a restart often helps, but if that fails, examine logs to pinpoint the missing bean's origin and consider re-running the migration or manually installing the required bundle. If upgrading, double-check compatibility and migration guides for specific upgrade steps to avoid missing dependencies.
