sasl_mechanism   (string)    sasl authentication mechanism, default 'plain'

sasl             (on|off)    set to 'on' to enable SASL authentication

tls_skip_verify  (on|off)    trust server TLS without verification, defaults to "on" (verify)

 * NullPointerTester} uses best effort to pick non-null default values for many common JDK and Guava
 * types, and also for interfaces and public classes that have public parameter-less constructors.
 * When the non-null default value for a particular parameter type cannot be provided by {@code
 * NullPointerTester}, the caller can provide a custom non-null default value for the parameter type
 * via {@link #setDefault}.

As in this case (without using `Annotated`) we have to replace the default value `None` in the function with `Query()`, we now need to set the default value with the parameter `Query(default=None)`, it serves the same purpose of defining that default value (at least for FastAPI).

So:

```Python
q: Union[str, None] = Query(default=None)
```

...makes the parameter optional, with a default value of `None`, the same as:

```Python

a new one will be generated on demand.

|CA_PROVIDER|Type of CA; supported values are GoogleCA or Citadel (although anything but GoogleCA will use Citadel); defaults to Citadel|
|PROV_CERT|certificates to be used for mTLS communication with control plane only; NOT for workload mTLS|
