 *          <note>
 *             <p>For maintenance window tasks without a specified target, you can't supply values for
 *      <code>--max-errors</code> and <code>--max-concurrency</code>. Instead, the system inserts a
 *     placeholder value of <code>1</code>, which may be reported in the response to this command.
 *     These values don't affect the running of your task and can be ignored.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SSMClient, DescribeMaintenanceWindowTasksCommand } from "@aws-sdk/client-ssm"; // ES Modules import
 * // const { SSMClient, DescribeMaintenanceWindowTasksCommand } = require("@aws-sdk/client-ssm"); // CommonJS import
 * const client = new SSMClient(config);
 * const command = new DescribeMaintenanceWindowTasksCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link DescribeMaintenanceWindowTasksCommandInput} for command's `input` shape.
 * @see {@link DescribeMaintenanceWindowTasksCommandOutput} for command's `response` shape.
 * @see {@link SSMClientResolvedConfig | config} for command's `input` shape.
