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:
```

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`
