Record : unsupported schemaVersion .

Error message

Record ${index + 1}: unsupported schemaVersion ${a.schemaVersion}.

What it means

normalizedEvent supports exactly schemaVersion 1. If a record carries a schemaVersion field with any other value, ingest rejects it (pet/src/core/ingest.ts:127) rather than guessing the shape — omitted schemaVersion is still accepted as v1.

Solutions

  1. Set schemaVersion to the number 1 or omit the field entirely
  2. Upgrade the ingest library to a version that supports the producer's schema
  3. Fix the producer to serialize schemaVersion as a number, not a string

Example fix

// before
{..., schemaVersion: '1'}
// after
{..., schemaVersion: 1}
Defensive patterns

Strategy: validation

Validate before calling

if (rec.schemaVersion!==undefined && rec.schemaVersion!==1) throw new Error('unsupported schemaVersion');

Type guard

const isV1Record=(r:any): r is {schemaVersion?:1} & Record<string,unknown> => r?.schemaVersion===undefined||r?.schemaVersion===1;

Try / catch

try { ingest(records); } catch (e) { if (/unsupported schemaVersion/.test(e.message)) { /* upgrade library or downgrade producer schema */ } else throw e; }

Prevention

When it happens

Trigger: Ingesting records where a.schemaVersion is 2, '1' (string), or any value !== 1 after a producer upgrade.

Common situations: Producer upgraded to a newer schema before the ingest library did; schemaVersion serialized as a string instead of a number; copying a fixture from a different project with a different versioning scheme.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
