EC2 InvalidVpcEndpointID.Malformed error encountered when trying to access or manage a VPC endpoint.

What is EC2 InvalidVpcEndpointID.Malformed error encountered when trying to access or manage a VPC endpoint.

Understanding Amazon EC2 and VPC Endpoints

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. One of the features of EC2 is the ability to create VPC endpoints, which allow 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: InvalidVpcEndpointID.Malformed

When working with VPC endpoints, you might encounter the error code InvalidVpcEndpointID.Malformed. This error typically occurs when the VPC endpoint ID provided does not conform to the expected format. As a result, operations involving the endpoint may fail, leading to disruptions in connectivity or service access.

Details About the InvalidVpcEndpointID.Malformed Issue

The InvalidVpcEndpointID.Malformed error indicates that the VPC endpoint ID you have specified is not correctly formatted. VPC endpoint IDs follow a specific pattern, and any deviation from this pattern will result in this error. The correct format for a VPC endpoint ID is typically vpce-xxxxxxxx, where 'x' represents a hexadecimal character.

Common Causes

Typographical errors in the endpoint ID. Using an ID from a different AWS region. Copy-paste errors leading to extra characters.

Steps to Fix the InvalidVpcEndpointID.Malformed Issue

To resolve this issue, follow these steps:

Step 1: Verify the Endpoint ID Format

Ensure that the VPC endpoint ID you are using follows the correct format. It should look like vpce-xxxxxxxx. Double-check for any typographical errors or extra characters.

Step 2: Confirm the Correct Region

Make sure that the VPC endpoint ID belongs to the correct AWS region. You can list all VPC endpoints in your region using the AWS CLI:

aws ec2 describe-vpc-endpoints --region your-region

Replace your-region with the appropriate AWS region code.

Step 3: Use the AWS Management Console

Navigate to the AWS VPC Console and select 'Endpoints' from the navigation pane. Verify the endpoint ID from the list and ensure it matches the one you are using.

Step 4: Update Your Configuration

If you find discrepancies, update your configuration or scripts with the correct VPC endpoint ID. This might involve editing configuration files or updating environment variables.
