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 key components in managing network traffic within and across AWS environments is the Transit Gateway. A Transit Gateway acts as a hub that controls how traffic is routed among all the connected networks, which can include VPCs, on-premises networks, and other AWS services.
When working with Transit Gateways in AWS, you might encounter the error code InvalidTransitGatewayRouteTableID.NotFound. This error typically appears when you attempt to reference a transit gateway route table ID that AWS cannot find. This can occur during operations such as creating or modifying route tables, or when associating route tables with VPCs or other resources.
The error InvalidTransitGatewayRouteTableID.NotFound indicates that the specified transit gateway route table ID does not exist in your AWS account or the region you are operating in. This could be due to a typographical error, a deletion of the route table, or an attempt to access a resource in a different region.
To resolve the InvalidTransitGatewayRouteTableID.NotFound error, follow these steps:
aws ec2 describe-transit-gateway-route-tables --region your-region to list all route tables in the specified region.For more information on managing Transit Gateways, refer to the AWS Transit Gateway Documentation. If you continue to experience issues, consider reaching out to AWS Support for further assistance.
