Cascade Configuration - Environment Variables Not Loaded
Spring Boot application fails to start because environment variables are not being loaded after Cascade modified configuration. Application properties are null even though environment variables are set, causing NullPointerException at startup.
Cascade likely changed property placeholder syntax or removed @ConfigurationProperties annotations.
Error Messages You Might See
Common Causes
- Cascade changed property key names in @ConfigurationProperties without updating environment variables
- Removed @EnableConfigurationProperties or @ConfigurationPropertiesScan annotations
- Cascade added @ConfigurationProperties on class without proper constructor or setters
- Property prefix mismatch: ${spring.database.url} vs actual env var DATABASE_URL
How to Fix It
Verify @EnableConfigurationProperties is present on @Configuration class. Check property names match @ConfigurationProperties prefix and field names. Ensure environment variables follow Spring Boot conventions (UPPERCASE_WITH_UNDERSCORES). Test with application.yml properties file first before relying on env vars.
