Thanks Rahul for spotting the issue! I can reproduce what @JohnKuldeepRoshanKerketta experienced in Forge SDK (forge-apis) in 0.9.0. By the hint of error, I updated the tutorial code(line 509,510) to use readFile, instead of file stream. Now it works well with 0.9.0.

I posted the Issue with tutorial https://github.com/Autodesk-Forge/learn.forge.designautomation/issues/31

// 2. upload inputFile
const inputFileNameOSS = `${new Date().toISOString().replace(/[-T:\.Z]/gm, '').substring(0,14)}_input_${_path.basename(req.file.originalname)}`; // avoid overriding

try {
    //let contentStream = _fs.createReadStream(req.file.path);

    let fileContent = _fs.readFileSync(req.file.path);

    await new ForgeAPI.ObjectsApi().uploadObject(bucketKey, inputFileNameOSS, req.file.size, fileContent, {}, req.oauth_client, req.oauth_token);
}
