Handle transaction errors in Prisma by wrapping transactions in try/catch blocks, inspecting error codes (P-codes), and implementing recovery patterns like retries with exponential backoff. Map known P-codes such as P2002, P2025, and P2034 to user-friendly messages for logging and user feedback.

Prisma P-codes are error identifiers that indicate specific failure types—P2002 signals unique constraint violations, P2025 indicates missing records, and P2034 represents transaction conflicts. Mapping P-codes to descriptive messages helps users understand failures and guides recovery decisions in transactional workflows.

Configure maxWait and timeout parameters in prisma.$transaction to control transaction duration. Implement retry logic with exponential backoff to handle transient failures, and use idempotent operations like upserts to safely re-execute steps without creating duplicates or inconsistent state.

Yes. Idempotent operations such as upserts within prisma.$transaction enable safe retries—re-running the same operation produces the same result without side effects. This pattern is essential for multi-step workflows involving creation and updates of related records when transient errors occur.

Use structured try/catch blocks around prisma.$transaction to wrap multi-step operations. Implement comprehensive P-code handlers, configure appropriate timeouts, apply idempotent upserts for updates, and define fallback strategies so related-record workflows recover gracefully from constraint violations or missing-record errors.

Transactions fail due to constraint violations, missing records, or timeout conditions—common in concurrent multi-step workflows. Implement recovery strategies when handling related-record operations at scale, particularly when P2002, P2025, or P2034 errors are expected, to maintain data consistency and user experience.
