EC2 InvalidVpcEndpointID.NotFound error encountered when attempting to access a VPC endpoint.

The specified VPC endpoint ID does not exist or is incorrect.

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. A VPC (Virtual Private Cloud) endpoint enables 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.

Identifying the Symptom

When working with EC2 and VPC endpoints, you might encounter the error code InvalidVpcEndpointID.NotFound. This error typically occurs when you attempt to access a VPC endpoint using an ID that does not exist or is incorrect.

Common Error Message

The error message you might see is: InvalidVpcEndpointID.NotFound: The specified VPC endpoint ID does not exist.

Explaining the Issue

The InvalidVpcEndpointID.NotFound error indicates that the VPC endpoint ID you are using in your request is not recognized by AWS. This can happen if the ID is mistyped, the endpoint has been deleted, or you are querying the wrong region.

Why This Happens

  • Typographical Error: The VPC endpoint ID might be incorrectly entered.
  • Endpoint Deletion: The endpoint may have been deleted after its creation.
  • Region Mismatch: The endpoint ID is being queried in a different region than where it was created.

Steps to Fix the Issue

To resolve the InvalidVpcEndpointID.NotFound error, follow these steps:

Step 1: Verify the VPC Endpoint ID

Ensure that the VPC endpoint ID you are using is correct. You can list all VPC endpoints in your account to verify the ID:

aws ec2 describe-vpc-endpoints --region

Replace <your-region> with the appropriate AWS region.

Step 2: Check for Deletion

If the endpoint ID is not listed, it may have been deleted. You can check your AWS CloudTrail logs to see if there was a deletion event for the endpoint.

Step 3: Confirm the Region

Ensure that you are querying the correct AWS region where the VPC endpoint was created. VPC endpoint IDs are region-specific.
