01:24:11 WARN  JdbcTableSchemaHistory: Could not find schema history table "PUBLIC"."flyway_schema_history", but found "PUBLIC"."schema_version" instead. You are seeing this message because Flyway changed its default for flyway.table in version 5.0.0 to flyway_schema_history and you are still relying on the old default (schema_version). Set flyway.table=schema_version in your configuration to fix this. This fallback mechanism will be removed in Flyway 6.0.0.
