Description

The data source aws_ec2_transit_gateway_attachment calculates an arn value based on the format arn:${Partition}:ec2:${Region}:${Account}:transit-gateway-attachment/${TransitGatewayAttachmentId}, documented at https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonec2.html#amazonec2-resources-for-iam-policies

The Transit Gateway Attachment resource types and the type-specific data sources do not calculate the ARN. Do so.

Affected Resource(s) and/or Data Source(s)

• data.aws_ec2_transit_gateway_dx_gateway_attachment

• data.aws_ec2_transit_gateway_peering_attachment
