terraform validate

Workaround

vars.tf

variable "aws_region" {
  default = "foo"
}

variable "aws_access_key" {
  default = "foo"
}

variable "aws_secret_key" {
  default = "foo"
}

variable "aws_key_path" {
  default = "foo"
}

variable "aws_key_name" {
  default = "foo"
}

  default = "foo"
}

variable "aws_role_session" {
  default = "foo"
}

Hi @jpdoria! Sorry this isn't working as expected.

I think this might be the same issue as #15733. If so, the workaround until that's fixed would be to explicitly specify the vars file:

$ terraform validate -var-file=terraform.tfvars

I'm having the same issues with v0.10.7

I am also having the same issues with v0.10.7

Hi all,

We added a fix for this in #15938 which was confirmed as fixed in v0.10.5 per discussion on #15733. It looks like some of you have a problem with similar symptoms, but the cause must be different if it's still present after v0.10.5.

In order to understand what's different about your situation, could one of you please open a new top-level issue with the details requested by the issue template? That way we will hopefully have enough information to reproduce the issue, whereas the details given in the description of this one no longer seem to reproduce.

Thanks!
