Error message for Vault secrets versions marked as deleted in Vault KV2

Hi,

Current, when using the Vault integration to get secrets , if the targeted secrets path current version is marked as deleted in Vault, the output message is very technical with a panic :

ERROR: Job failed (system failure): panic: interface conversion: interface {} is nil, not map[string]interface {}

I think it would better for DX to detect that and display a more clear error message
