tfexec `Terraform.Output` method returns error when command is successful

I am using terraform-exec with HCP terraform to manage some infra. When running terraform output command, logs show that there was a connection error and it's trying to re-establish the connection, eventually the command logs the correct output, but Terraform.Output method returns an error.

Expected behaviour: error returned by Terraform.Output should be nil.

Error returned by the library: invalid character 'T' looking for beginning of value

Logs:

time=2024-07-11T13:06:33.111Z level=INFO msg="[INFO] running Terraform command: /home/terraform/app/terraform output -no-color -json"

There was an error connecting to HCP Terraform. Please do not exit

  },

}

It's probably failing when trying to convert the command's output into map[string]OutputMeta
