Likely Causes
  1. The current statement triggered serialization_failure, which PostgreSQL classifies as SQLSTATE 40001.
  2. Application SQL, parameter values, or transaction state are incompatible with PostgreSQL rules for serialization failure.
  3. Environment differences (schema, permissions, or runtime settings) exposed this 40001 condition in production flow.
How to Fix It
1
Capture full query text, bind values, and transaction context for SQLSTATE 40001.
2
Reproduce serialization_failure in staging with the same schema version and connection settings.
3
Inspect pg logs and execution plan details to isolate the exact failing clause or object.
4
Apply a targeted fix (query rewrite, schema migration, or transaction-order change) for serialization failure.
5
Deploy and verify SQLSTATE 40001 no longer appears in error telemetry.
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
