Question

I am getting following errors while describe the transit gateway peering attachments more than one and not getting the error while describe the transit gateway peering attachments with single peering attachment.

Code

data "aws_ec2_transit_gateway_attachment" "example" {
  
  filter {
     name    = "state"
     values  = ["pendingAcceptance","available"]
  }

  filter {
     name   = "transit-gateway-id"
     values = ["<Transit_gateway_id>"]
  }
}

Error

Error: multiple EC2 Transit Gateway Attachments matched; use additional constraints to reduce matches to a single EC2 Transit Gateway Attachment │ │ with data.aws_ec2_transit_gateway_attachment.example, │ on main.tf line 5, in data "aws_ec2_transit_gateway_attachment" "example": │ 5: data "aws_ec2_transit_gateway_attachment" "example" {

Answer 1

Apparently, as error tells, you have multiple attachments matching filter. You should make filter more precise. If you create tgw attachment in terraform just add it's id to filter . If you are looking only for pending attachments remove "available" from state's values.
