Flyway Database Migration Failed on Replit
Your application fails to start because Flyway migration encounters an error. The database schema update is blocked, preventing the app from initializing.
Migration failures often indicate SQL syntax errors, constraint violations, or state mismatches between environments.
Error Messages You Might See
Common Causes
- SQL syntax error in migration file
- Migration file naming convention incorrect (must be V1__init.sql)
- Constraint violation when adding columns
- Previous failed migration not cleaned up in flyway_schema_history
- Missing permissions for migration operations
How to Fix It
Check migration file names follow V{number}__{description}.sql format. Review the SQL syntax in error logs. If a migration failed midway, repair or delete the failed entry in flyway_schema_history table and re-run. Use Replit's database console to verify changes.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.
