i double checked the perms on this user where I’m trying to create the fargate instance and it can create a VPC. I assume its failing somewhere in the chain.

Just to be sure - which example is this? I believe we use the “default VPC” by default, and that that is the only VPC we try to look up. Any AWS account created in the last 5 years or so should have this default VPC in each region, but it is possible that it’s been deleted or that your account is old enough that this default VPC was not created. https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html Could that be the issue?

ah interesting. I indeed do not have a default vpc

We should improve the error message here though!
