Using javascript to download file from dropbox

Hi amei​,

I have reviewed the information you provided. From my understanding, you are experiencing difficulties downloading a file using the Dropbox JavaScript SDK and parsing a JSON file.

Based on the code snippet you shared, it appears that the JSON file is being parsed incorrectly. Would you be able to test the following code snippet example to check whether it resolves the issue you are encountering?

import { Dropbox } from "dropbox";
import fs from "fs/promises";

const dbx = new Dropbox({ accessToken: "YOUR_ACCESS_TOKEN" });

async function downloadJsonFile() {
  try {
    // Request file from Dropbox
    const { result } = await dbx.filesDownload({ path: "/users_array.json" });

    // Convert response into a buffer
    let buffer;
    if (result.fileBinary) {
      buffer = Buffer.from(result.fileBinary);
    } else if (result.fileBlob) {
      const ab = await result.fileBlob.arrayBuffer();
      buffer = Buffer.from(ab);
    } else {
      throw new Error("Unexpected response: no fileBinary/fileBlob present.");
    }

    // Download the file to a specified location on your local machine.
    await fs.writeFile("/YOUR_FILE_PATH_TO/users_array.json", buffer);
    console.log("File downloaded successfully");

    // Parsing JSON file after downloading the file
    const parsed = JSON.parse(buffer.toString("utf8"));
    console.log("Parsed JSON object:", parsed);

  } catch (error) {
    console.error(" Error downloading file:", error);
  }
}

downloadJsonFile();
