 * <p>Updates the configuration of a Lambda function <a href="https://docs.aws.amazon.com/lambda/latest/dg/configuration-aliases.html">alias</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { LambdaClient, UpdateAliasCommand } from "@aws-sdk/client-lambda"; // ES Modules import
 * // const { LambdaClient, UpdateAliasCommand } = require("@aws-sdk/client-lambda"); // CommonJS import
 * // import type { LambdaClientConfig } from "@aws-sdk/client-lambda";

 * const input = { // UpdateAliasRequest
 *   FunctionName: "STRING_VALUE", // required
 *   Name: "STRING_VALUE", // required

 *   Description: "STRING_VALUE",
 *   RoutingConfig: { // AliasRoutingConfiguration
 *     AdditionalVersionWeights: { // AdditionalVersionWeights

 * @throws {@link InvalidParameterValueException} (client fault)
 *  <p>One of the parameters in the request is not valid.</p>
 *
 * @throws {@link PreconditionFailedException} (client fault)
 *  <p>The RevisionId provided does not match the latest RevisionId for the Lambda function or alias.</p> <ul> <li> <p> <b>For AddPermission and RemovePermission API operations:</b> Call <code>GetPolicy</code> to retrieve the latest RevisionId for your resource.</p> </li> <li> <p> <b>For all other API operations:</b> Call <code>GetFunction</code> or <code>GetAlias</code> to retrieve the latest RevisionId for your resource.</p> </li> </ul>
