Config (you can paste only the changes you've made):

  async createObject(fileName, content) {
      console.log(`Starting upload for ${fileName}`);

      // Write content to file
      const tempDir = path.resolve("./temp");
      if (!fs.existsSync(tempDir)) {
        fs.mkdirSync(tempDir, { recursive: true });
      }
      tempFilePath = path.join(tempDir, fileName);
      // Ensure content is properly stringified
      const contentString =
        typeof content === "string" ? content : JSON.stringify(content);
      fs.writeFileSync(tempFilePath, contentString, "utf8");
      const fileBuffer = fs.readFileSync(tempFilePath);
      console.log(`File size: ${fileBuffer.byteLength} bytes`);

      // Generate checksums
      console.log("Generating checksums...");
      const rs = new NodeAdapterReedSolomon();
      const expectCheckSums = await rs.encodeInWorker(
        __filename, // Use current file
        Uint8Array.from(fileBuffer)
      );

      console.log("Checksums generated successfully");

      // Create object transaction
      console.log("Creating object transaction...");
      const createObjectTx = await this.client.object.createObject({
        bucketName: this.bucketName,
        objectName: fileName,
        creator: process.env.ACCOUNT_ADDRESS,
        visibility: VisibilityType.VISIBILITY_TYPE_PUBLIC_READ,
        contentType: "application/json",
        redundancyType: RedundancyType.REDUNDANCY_EC_TYPE,
        payloadSize: Long.fromInt(fileBuffer.byteLength),
        expectChecksums: expectCheckSums.map((x) => bytesFromBase64(x)),
      });

     //further code

Anything else we need to know:
idk why am i gettimg this error even i am able buffer size of the file

1. Please provide the version of @bnb-chain/reed-solomon
2. Verify that tempFilePath does have a file generated
3. Please provide the complete code file if it is convenient

[devhimanshuhc]

@ybgbob

1. the version:

    "@bnb-chain/greenfield-js-sdk": "^2.2.0",
    "@bnb-chain/reed-solomon": "^1.1.3",

2. Yes, the file being generated, even getting the file size as 1740 bytes
3. This is the whole code, before that i just have create bucket function which is working correctly. Please tell what you require, i will share it.

@devhimanshuhc

The code looks correct.

We now recommend using delegateUploadObject. example

@rrr523 you guys really need to cross-check you sdk examples,i still remember using the sdk a year back and just because of the sdk issues i dropped the idea of using greenfield sdk. and again, as the replies were late, i dropped using the sdk.
