/**
 * <important>
 *             <p>Using the <code>GetBucketLocation</code> operation is no longer a best practice. To return the
 *         Region that a bucket resides in, we recommend that you use the
 *         <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadBucket.html">HeadBucket</a>
 *         operation instead. For backward compatibility, Amazon S3 continues to support the
 *         <code>GetBucketLocation</code> operation.</p>
 *          </important>
 *          <p>Returns the Region the bucket resides in. You set the bucket's Region using the
 *         <code>LocationConstraint</code> request parameter in a <code>CreateBucket</code> request. For more
 *       information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html">CreateBucket</a>.</p>
 *          <note>
 *             <p>In a bucket's home Region, calls to the <code>GetBucketLocation</code> operation are governed
 *         by the bucket's policy. In other Regions, the bucket policy doesn't apply, which means that
 *         cross-account access won't be authorized. However, calls to the <code>HeadBucket</code> operation
 *         always return the bucket’s location through an HTTP response header, whether access to the bucket
 *         is authorized or not. Therefore, we recommend using the <code>HeadBucket</code> operation for
 *         bucket Region discovery and to avoid using the <code>GetBucketLocation</code> operation.</p>
 *          </note>
 *          <p>When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.</p>
 *          <p>When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name.
 * If the Object Lambda access point alias in a request is not valid, the error code <code>InvalidAccessPointAliasError</code> is returned.
 * For more information about <code>InvalidAccessPointAliasError</code>, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html#ErrorCodeList">List of
 *             Error Codes</a>.</p>
 *          <note>
 *             <p>This operation is not supported for directory buckets.</p>
 *          </note>
 *          <p>The following operations are related to <code>GetBucketLocation</code>:</p>
 *          <ul>
 *             <li>
 *                <p>
 *                   <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html">GetObject</a>
 *                </p>
 *             </li>
 *             <li>
 *                <p>
 *                   <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html">CreateBucket</a>
 *                </p>
 *             </li>
 *          </ul>
 *          <important>
 *             <p>You must URL encode any signed header values that contain spaces. For example, if your header value is <code>my  file.txt</code>, containing two spaces after <code>my</code>, you must URL encode this value to <code>my%20%20file.txt</code>.</p>
 *          </important>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { S3Client, GetBucketLocationCommand } from "@aws-sdk/client-s3"; // ES Modules import
 * // const { S3Client, GetBucketLocationCommand } = require("@aws-sdk/client-s3"); // CommonJS import
 * // import type { S3ClientConfig } from "@aws-sdk/client-s3";
 * const config = {}; // type is S3ClientConfig
 * const client = new S3Client(config);
 * const input = { // GetBucketLocationRequest
 *   Bucket: "STRING_VALUE", // required
 *   ExpectedBucketOwner: "STRING_VALUE",
 * };
 * const command = new GetBucketLocationCommand(input);
 * const response = await client.send(command);
 * // { // GetBucketLocationOutput
 * //   LocationConstraint: "af-south-1" || "ap-east-1" || "ap-northeast-1" || "ap-northeast-2" || "ap-northeast-3" || "ap-south-1" || "ap-south-2" || "ap-southeast-1" || "ap-southeast-2" || "ap-southeast-3" || "ap-southeast-4" || "ap-southeast-5" || "ca-central-1" || "cn-north-1" || "cn-northwest-1" || "EU" || "eu-central-1" || "eu-central-2" || "eu-north-1" || "eu-south-1" || "eu-south-2" || "eu-west-1" || "eu-west-2" || "eu-west-3" || "il-central-1" || "me-central-1" || "me-south-1" || "sa-east-1" || "us-east-2" || "us-gov-east-1" || "us-gov-west-1" || "us-west-1" || "us-west-2",
 * // };
