/**
 * <p>Evaluates a given template and returns the response. The mapping template can be a
 *          request or response template.</p>
 *          <p>Request templates take the incoming request after a GraphQL operation is parsed and
 *          convert it into a request configuration for the selected data source operation. Response
 *          templates interpret responses from the data source and map it to the shape of the GraphQL
 *          field output type.</p>
 *          <p>Mapping templates are written in the Apache Velocity Template Language (VTL).</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { AppSyncClient, EvaluateMappingTemplateCommand } from "@aws-sdk/client-appsync"; // ES Modules import
 * // const { AppSyncClient, EvaluateMappingTemplateCommand } = require("@aws-sdk/client-appsync"); // CommonJS import
 * // import type { AppSyncClientConfig } from "@aws-sdk/client-appsync";
 * const config = {}; // type is AppSyncClientConfig
 * const client = new AppSyncClient(config);
 * const input = { // EvaluateMappingTemplateRequest
 *   template: "STRING_VALUE", // required
 *   context: "STRING_VALUE", // required
 * };
 * const command = new EvaluateMappingTemplateCommand(input);
 * const response = await client.send(command);
 * // { // EvaluateMappingTemplateResponse
 * //   evaluationResult: "STRING_VALUE",
 * //   error: { // ErrorDetail
 * //     message: "STRING_VALUE",
 * //   },
 * //   logs: [ // Logs
 * //     "STRING_VALUE",
 * //   ],
 * //   stash: "STRING_VALUE",
 * //   outErrors: "STRING_VALUE",
 * // };
 *
