request.agentCoreProfile.eventExpiryDays must be 90

Error message

request.agentCoreProfile.eventExpiryDays must be 90

What it means

parseAgentCoreProfile pins request.agentCoreProfile.eventExpiryDays to exactly the number 90, matching the AWS AgentCore event-expiry requirement. Any other value — 30, '90' as a string, or null — throws this error, keeping the harness configuration compliant with the supported retention window.

Solutions

1. Set eventExpiryDays to the number 90 exactly (not the string '90')
2. Remove custom retention overrides so the pinned value applies
3. If another retention window is genuinely needed, update the contract deliberately — do not bypass validation
4. Verify the producer emits a JSON number for this field

Example fix

// before
{ eventExpiryDays: '90' }
// after
{ eventExpiryDays: 90 }

const REQUIRED_EVENT_EXPIRY_DAYS = 90;
if (req.agentCoreProfile?.eventExpiryDays !== REQUIRED_EVENT_EXPIRY_DAYS) {
  throw new Error('eventExpiryDays must be 90 (number)');
}

function hasValidEventExpiry(p) {
  return p?.eventExpiryDays === 90;
}

try {
  const request = parseEvalSessionRequest(raw);
} catch (err) {
  if (err.message.includes('eventExpiryDays must be 90')) {
    throw new RequestValidationError('AgentCore eventExpiryDays is pinned to the number 90 in this build', { cause: err });
  }
  throw err;
}

When it happens

Trigger: Calling parseEvalSessionRequest with request.agentCoreProfile.eventExpiryDays set to any value other than the numeric literal 90, including the string '90', 30, 365, or a missing field (undefined !== 90).

Common situations: A template or copy-pasted AgentCore config used a different retention value; the field was serialized as a string; a newer AgentCore default (e.g. 30 days) leaked into the request; the field was simply omitted.

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.
