 * Upload data to the specified S3 object path. By default uses a single PUT
 * operation to upload when the payload is less than 5MB. Otherwise, uses
 * multipart upload to upload the payload.
 *
 * Server-side `uploadData` is intended for use in SSR contexts such as
 * Next.js Route Handlers and Server Actions.
 *
 * @param contextSpec - The isolated server context.
 * @param input - A `UploadDataWithPathInput` object.
 *
 * @returns An `UploadDataServerWithPathOutput` task. Await the `result`
 * 	promise to get the upload result.
 *
 * @throws S3Exception when the underlying S3 service returned error.
 * @throws StorageValidationErrorCode when API call parameters are invalid.
 *
 * @example
 * ```ts
 * // In a Next.js Route Handler
 * import { runWithAmplifyServerContext } from '@aws-amplify/adapter-nextjs';
 * import { uploadData } from 'aws-amplify/storage/server';
 * import { cookies } from 'next/headers';
 *
 * export async function POST(request: Request) {
 *   const formData = await request.formData();
 *   const file = formData.get('file') as File;
 *   const result = await runWithAmplifyServerContext({
 *     nextServerContext: { cookies },
 *     operation: (contextSpec) =>
 *       uploadData(contextSpec, { path: `uploads/${file.name}`, data: file }).result,
 *   });
 *   return Response.json(result);
 * }
