 * <p>Used by activity workers, Task states using the <a href="https://docs.aws.amazon.com/step-functions/latest/dg/connect-to-resource.html#connect-wait-token">callback</a>
 *       pattern, and optionally Task states using the <a href="https://docs.aws.amazon.com/step-functions/latest/dg/connect-to-resource.html#connect-sync">job run</a> pattern to report that the task identified by the <code>taskToken</code> failed.</p>
 *          <p>For an execution with encryption enabled, Step Functions will encrypt the error and cause fields using the KMS key for the execution role.</p>
 *          <p>A caller can mark a task as fail without using any KMS permissions in the execution role if the caller provides a null value for both <code>error</code> and <code>cause</code> fields because no data needs to be encrypted.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SFNClient, SendTaskFailureCommand } from "@aws-sdk/client-sfn"; // ES Modules import
 * // const { SFNClient, SendTaskFailureCommand } = require("@aws-sdk/client-sfn"); // CommonJS import
 * // import type { SFNClientConfig } from "@aws-sdk/client-sfn";
 * const config = {}; // type is SFNClientConfig
 * const client = new SFNClient(config);
 * const input = { // SendTaskFailureInput
 *   taskToken: "STRING_VALUE", // required
 *   error: "STRING_VALUE",
 *   cause: "STRING_VALUE",
 * };
 * const command = new SendTaskFailureCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param SendTaskFailureCommandInput - {@link SendTaskFailureCommandInput}
 * @returns {@link SendTaskFailureCommandOutput}
 * @see {@link SendTaskFailureCommandInput} for command's `input` shape.
 * @see {@link SendTaskFailureCommandOutput} for command's `response` shape.
 * @see {@link SFNClientResolvedConfig | config} for SFNClient's `config` shape.
 *
 * @throws {@link InvalidToken} (client fault)
 *  <p>The provided token is not valid.</p>
 *
 * @throws {@link KmsAccessDeniedException} (client fault)
 *  <p>Either your KMS key policy or API caller does not have the required permissions.</p>
 *
 * @throws {@link KmsInvalidStateException} (client fault)
 *  <p>The KMS key is not in valid state, for example: Disabled or Deleted.</p>
 *
 * @throws {@link KmsThrottlingException} (client fault)
 *  <p>Received when KMS returns <code>ThrottlingException</code> for a KMS call that Step Functions makes on behalf of the caller.</p>
 *
 * @throws {@link TaskDoesNotExist} (client fault)
 *  <p>The activity does not exist.</p>
 *
 * @throws {@link TaskTimedOut} (client fault)
