Using javascript to download file from dropbox

Hi amei​ 

The response from 'filesDownload()' does not contain a 'fileBlob' property (which is why you are getting an 'undefined' in the error message). The response contains a 'fileBinary', which can be accessed as such: 'response.result.fileBinary'. Additionally, you can convert the returned Buffer to text or a string by invoking the 'toString()' method on the response. We would also recommend making that callback function an async function:

...
dbx.filesDownload({ path: dropbox_users_path_file })
.then(async (response) => {
  console.log(response.result.fileBinary.toString())
}
...

Similarly for the second function:

...
try {
  const response = await dbx.filesDownload({
    path: dropbox_users_path_file
  })
  console.log(response.result.fileBinary.toString())
}
...

In order to further assist with the file upload error, please provide the code snippet used to upload files to Dropbox. The screenshots provided are both for downloading files ('filesDownload()').
