terraform aws fails

[albertollamaso]

Trying to use the terraform scripts for creating resources in AWS.

Environment:

• I've cloned latest version of kubespry repository

• I've set properly the fields in file: credentials.tfvars

• The command I run: terraform plan -var-file=credentials.tfvars

• Terraform version:

Terraform v0.12.12
+ provider.aws v2.41.0
+ provider.null v2.1.2
+ provider.template v2.1.2

• OS (printf "$(uname -srm)\n$(cat /etc/os-release)\n"):
  Darwin 19.0.0 x86_64

• error output:
