LambdaServiceException - Lambda Service Exception
Getting a **LambdaServiceException** means AWS Lambda encountered an internal service error—this is a server-side issue (5xx) that's usually temporary and resolves with retries. This server-side error happens when Lambda services experience internal failures. Most common during temporary service issues, but also appears when services are temporarily unavailable, Lambda is overloaded, regional service issues occur, or transient infrastructure problems happen.
#Common Causes
- →Identity: IAM service internal error. Service Control Policy (SCP) service failure. Account-level Lambda service issues.
- →Network: VPC endpoint Lambda service internal error. Regional Lambda service failures. Cross-region service issues.
- →Limits: Internal Lambda service error. Temporary service unavailability. Service overload. Regional service issue. Transient infrastructure problem.
✓Solutions
- 1Step 1: Diagnose - Check AWS Service Health Dashboard: Visit https://status.aws.amazon.com/. Check Lambda service status. Review recent incidents. Check if issue is known.
- 2Step 2: Diagnose - Verify error is LambdaServiceException: Check error code is LambdaServiceException (5xx). Verify it's not a client error (4xx). Check if error is consistent or intermittent.
- 3Step 3: Diagnose - Check Lambda service metrics: aws cloudwatch get-metric-statistics --namespace AWS/Lambda --metric-name Errors --dimensions Name=FunctionName,Value=FUNCTION_NAME --start-time TIME --end-time TIME --period 300 --statistics Sum. Monitor Lambda errors.
- 4Step 4: Fix - Implement exponential backoff: Retry with delays: 1s, 2s, 4s, 8s, 16s. Use AWS SDK automatic retries. Add jitter to prevent thundering herd. Max retries: 5-10 attempts.
- 5Step 5: Fix - Wait and retry or try different region: If temporary, wait a few minutes and retry. Try different region: aws lambda list-functions --region us-west-2. If persistent, contact AWS Support: aws support create-case --subject "LambdaServiceException" --service-code lambda --severity-code normal.
