EC2 InvalidVpcEndpointConnectionID.Malformed error encountered when attempting to connect to a VPC endpoint.
The specified VPC endpoint connection ID is not in the correct format.
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 connect to other AWS services using VPC endpoints, which are virtual devices that enable you to privately connect your VPC to supported AWS services and VPC endpoint services powered by AWS PrivateLink.
Recognizing the Symptom: InvalidVpcEndpointConnectionID.Malformed
When working with VPC endpoints, you might encounter the error InvalidVpcEndpointConnectionID.Malformed. This error typically occurs when the connection ID provided does not match the expected format. As a result, you may be unable to establish a connection to the desired VPC endpoint.
Common Scenarios
This error can occur during various operations, such as creating, modifying, or deleting a VPC endpoint connection. It is crucial to ensure that the connection ID is correctly formatted to avoid this issue.
Explaining the Issue: Malformed VPC Endpoint Connection ID
The InvalidVpcEndpointConnectionID.Malformed error indicates that the VPC endpoint connection ID you have specified does not adhere to the required format. Each VPC endpoint connection ID is expected to follow a specific pattern, and any deviation from this pattern will result in an error.
Format Requirements
Typically, a VPC endpoint connection ID should be a string that follows a predefined pattern, such as vpce-xxxxxxxx, where xxxxxxxx is a unique identifier. Any discrepancies in this format will trigger the malformed error.
Steps to Fix the InvalidVpcEndpointConnectionID.Malformed Error
To resolve this issue, follow these steps:
Step 1: Verify the Connection ID Format
Ensure that the VPC endpoint connection ID you are using follows the correct format. Double-check the ID for any typographical errors or missing characters. The ID should resemble vpce-xxxxxxxx.
Step 2: Retrieve the Correct Connection ID
If you are unsure of the correct connection ID, you can retrieve it using the AWS Management Console or AWS CLI:
aws ec2 describe-vpc-endpoints --query 'VpcEndpoints[*].VpcEndpointId'
This command will list all VPC endpoint IDs associated with your account. Ensure you use the correct one.
Step 3: Update Your Configuration
Once you have verified the correct connection ID, update your configuration or scripts to use this ID. Ensure that any automated processes or scripts are also updated to prevent future occurrences of this error.
