For more information, see the <a href="https://docs.cedarpolicy.com/policies/syntax-operators.html#has-presence-of-attribute-test">has (presence of attribute test) operator</a> in the <i>Cedar Policy Language Guide</i>.</p> </li> <li> <p> <b>ImpossiblePolicy</b> </p> <p>Cedar has determined that a policy condition always evaluates to false. If the policy is always false, it can never apply to any query, and so it can never affect an authorization decision.</p> </li> <li> <p> <b>WrongNumberArguments</b> </p> <p>The policy references an extension type with the wrong number of arguments.</p> </li> <li> <p> <b>FunctionArgumentValidationError</b> </p> <p>Cedar couldn't parse the argument passed to an extension type. For example, a string that is to be parsed as an IPv4 address can contain only digits and the period character.</p> </li> </ul>

 * @example GetSchema
 * ```javascript
 * // The following example retrieves the current schema stored in the specified policy store.
 *
 * Note
 * The JSON in the parameters of this operation are strings that can contain embedded quotation marks (") within the outermost quotation mark pair. This requires that you stringify the JSON object by preceding all embedded quotation marks with a backslash character ( \" ) and combining all lines into a single text line with no line breaks.
 *
 * Example strings might be displayed wrapped across multiple lines here for readability, but the operation requires the parameters be submitted as single line strings.
