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
org.flywaydb.core.internal.command.DbValidate$ValidateResult: Validated error
Flyway version check failed
Migration execution failed
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.
