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

Common Causes

  1. SQL syntax error in migration file
  2. Migration file naming convention incorrect (must be V1__init.sql)
  3. Constraint violation when adding columns
  4. Previous failed migration not cleaned up in flyway_schema_history
  5. 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.
