EC2 InvalidVpcEndpointServiceID.Malformed error encountered when attempting to use a VPC endpoint service.

The specified VPC endpoint service ID is not in the correct format.

Understanding Amazon EC2 and VPC Endpoint Services

Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. A VPC (Virtual Private Cloud) endpoint allows you to privately connect your VPC to supported AWS services and VPC endpoint services powered by AWS PrivateLink without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection.

Recognizing the Symptom: InvalidVpcEndpointServiceID.Malformed

When working with VPC endpoint services, you might encounter the error code InvalidVpcEndpointServiceID.Malformed. This error typically appears when you attempt to create or modify a VPC endpoint with an incorrectly formatted service ID.

Common Scenarios

  • Attempting to create a VPC endpoint with a malformed service ID.
  • Modifying an existing endpoint with an incorrect service ID format.

Details About the InvalidVpcEndpointServiceID.Malformed Issue

The InvalidVpcEndpointServiceID.Malformed error indicates that the service ID you provided does not adhere to the expected format. A VPC endpoint service ID typically follows a specific pattern, such as vpce-svc-xxxxxxxx, where xxxxxxxx is a unique identifier.

Why the Error Occurs

This error can occur due to typographical errors, copying the wrong ID, or using an outdated or incorrect reference to the service ID.

Steps to Fix the InvalidVpcEndpointServiceID.Malformed Issue

To resolve this issue, follow these steps:

Step 1: Verify the Service ID Format

Ensure that the service ID you are using follows the correct pattern. It should look like vpce-svc-xxxxxxxx. Double-check for any typographical errors or missing characters.

Step 2: Retrieve the Correct Service ID

If you are unsure about the service ID, you can retrieve the correct one using the AWS Management Console or AWS CLI:

aws ec2 describe-vpc-endpoint-services --query 'ServiceDetails[*].ServiceId'

This command will list all available VPC endpoint service IDs in your account.

Step 3: Update Your Configuration

Once you have the correct service ID, update your configuration or scripts to use this ID. Ensure that all references to the service ID are updated to prevent future errors.
