request - The metadata request object.
Request parameters:
project - Project ID for this request.
Value must have pattern
(?:(?:\[-a-z0-9\]{1,63}\.)*(?:\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?):)?(?:\[0-9\]{1,19}|(?:\[a-z0-9\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?)).
region - Name of the region scoping this request.
Value must have pattern \[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?.
securityPolicy - Name of the security policy to update.
Value must have pattern
\[a-z\](?:\[-a-z0-9\]{0,61}\[a-z0-9\])?|\[1-9\]\[0-9\]{0,19}.
validateOnly - If true, the request will not be committed.
$fields - Selector specifying which fields to include in a partial

Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
