The atlantis version: ghcr.io/runatlantis/atlantis:v0.21.0

I’m trying to run policy_checks but getting this error:

- Unsupported state file format: The state file could not be parsed as JSON:
syntax error at byte offset 1.
- Unsupported state file format: The state file does not have a "version"
attribute, which is required to identify the format version.

Plan read error: plan file was created by Terraform 1.5.5, but this is 1.3.5;
plan files cannot be transferred between different Terraform versions

The DEFAULT_TF_VERSION is a little deceptive -- that is the version Atlantis will use if there is no other version constraint on terraform for a specific project. If there's any other Terraform version constraints -- if the

terraform

block or one of the included modules requires a version, even if it's something like

~> 1.5

, it will use the newest version that fulfills the versioning requirement.

I am not sure what Terraform you get if you log in to the container...but Terraform will pull different versions to fulfill whatever, so I don't know if the default version installed in the root is the same as the one Terraform will use.

but I noticed that in the atlantis initialization, he’s looking for 1.5.5 and it’s not finding, when I log in the container and run

terraform -v

it outputs 1.3.5

I have a versions.tf file in my module and it looks like this:

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 4.27"
    }
  }
  required_version = "1.5.5"
}
