Cause of Failure

The pattern /^[a-z0-9][a-z0-9_]+[a-z0-9]$/ enforces:

1. Allowed characters: lowercase alphanumeric characters (a-z, 0-9) and underscores (_).
2. Disallowed characters: Hyphens (-), uppercase characters, periods, and spaces.
3. Length & boundary rules: Must start and end with an alphanumeric character ([a-z0-9]), with at least one character in between.

The name submission-validation-queue fails because it uses hyphens (-) instead of underscores (_).

Suitable Queue Names Matching /^[a-z0-9][a-z0-9_]+[a-z0-9]$/

To comply with the regex rule, use snake_case naming across your queues and topics:

1. Core Submission Validation Queues

• Local / Default Queue: submission_validation_queue
• Dead-Letter Queue (DLQ): submission_validation_queue_dlq

2. Environment-Specific SQS Queue Names

• Dev: lis_cattle_submission_validation_dev (DLQ: lis_cattle_submission_validation_dev_dlq)
• Test: lis_cattle_submission_validation_test (DLQ: lis_cattle_submission_validation_test_dlq)
• Pre-Prod: lis_cattle_submission_validation_preprod (DLQ: lis_cattle_submission_validation_preprod_dlq)
• Production: lis_cattle_submission_validation_prod (DLQ: lis_cattle_submission_validation_prod_dlq)

3. Intake Queues (for Third-Party / External Ingestion)

• Queue: lis_cattle_submission_intake_prod
• DLQ: lis_cattle_submission_intake_prod_dlq

4. SNS Event Topics

• LocalStack: submission_validation_topic
• Cloud Environments: lis_cattle_submission_validation_events_prod

Updated Project Defaults

The repository configuration and LocalStack bootstrapping scripts have been updated to use valid snake_case names:

{
  "AWS": {
    "Region": "eu-west-2",
    "ServiceUrl": "http://localhost:4566",
    "UseLocalStack": true,
    "SubmissionValidationQueueUrl": "http://localhost:4566/000000000000/submission_validation_queue",
    "SubmissionValidationTopicArn": "arn:aws:sns:eu-west-2:000000000000:submission_validation_topic"
  }
}

These names conform directly to /^[a-z0-9][a-z0-9_]+[a-z0-9]$/ and align with existing resource conventions in compose/start-localstack.sh (such as identity_service_helper_intake and ls_keeper_data_import_complete).
