Overview of the Issue

After upgrading to v0.17.3, we are experiencing a go runtime error on atlantis apply commands when using Terraform Cloud remote execution. Specifically, the apply is triggered successfully and the plan starts in Terraform Cloud on the workspace. Once the plan finishes and is waiting for confirmation, atlantis crashes and the plan is left in pending state on the workspace in Terraform Cloud.

If I initiate the remote apply from my local machine with the same Terraform version that Atlantis is using, it is successful.
