panic: reflect: call of reflect.Value.Type on zero Value

If I use `hashicorp/tfc-workflows-github/actions/upload-configuration@v1.2.0` action with a workspace that doesn't exist in Terraform Cloud it panics.

```
error uploading configuration version to Terraform Cloud: resource not found
panic: reflect: call of reflect.Value.Type on zero Value

Inizia da internal/command/output.go alla riga 39, quindi esamina i chiamanti in internal/command/meta.go alla riga 121 e internal/command/upload.go alla riga 65. Riproduci l’upload con un workspace di Terraform Cloud inesistente e verifica che l’errore di risorsa non trovata venga gestito senza il panic di reflect.
