Likely Causes
  1. The current statement triggered null_value_not_allowed, which PostgreSQL classifies as SQLSTATE 22004.
  2. Application SQL, parameter values, or transaction state are incompatible with PostgreSQL rules for null value not allowed.

Capture full query text, bind values, and transaction context for SQLSTATE 22004.
2
Reproduce null_value_not_allowed 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 null value not allowed.
5
Deploy and verify SQLSTATE 22004 no longer appears in error telemetry.
