Error: ENOENT: no such file or directory, scandir Kubernetes Pod

Question

I'm trying to upload files with multer from my typescript/express app. I have tested the application locally on mac it's working fine with a folder uploads under src. It worked well for the Local docker container too without any issue. But, once I deploy it to Kubernetes the paths are not working. The plan is if the uploads folder does not exist then the app will create the folder using -

const storage = multer.diskStorage({
  destination: function(req: Request, file: Express.Multer.File, callback: any) {
    // const _baseUploadPath: string = path.join('./src', '..', 'abc_uploads');
    const _baseUploadPath: string = path.join('../', 'uploads');

    const _folderIdentifier: string | undefined = RequestTracker.requestId;
    const _tmpPath: string = path.resolve(_baseUploadPath, `_tmp_${_folderIdentifier}`);

    fs.existsSync(_baseUploadPath) || fs.mkdirSync(_baseUploadPath);
    fs.existsSync(_tmpPath) || fs.mkdirSync(_tmpPath);

    callback(null, _tmpPath);
  },

  filename: function(req: Request, file: Express.Multer.File, callback: any) {
    callback(null, file.originalname.substring(0, file.originalname.indexOf(".")) + path.extname(file.originalname));
    return;
  }
});

Now, I am getting the error - Error: ENOENT: no such file or directory, scandir.

Even if the folder is present and I'm login to the pod terminal and change the permission of the folder as 777 still the sub folders not getting created .

Can anyone please help.
