Validate operation unsupported

Great project, congrats !!!!!.

I'm load the implementation guide from Costa Rica and not have any problems. I trying use the validate operation but the "candle server" send response the follow OperationOutcome:
```json
{
"resourceType": "OperationOutcome",
"id": "b5827e82-2cc8-475a-8454-093da2fca868",
"issue": [
{
"severity": "error",
"code": "not-found",
"diagnostics": "Operation $validate does not have an executable implementation on this server."
}
]
}
```
This operation is unsupported?
