dropbox.api and DropboxClient

[Lino1]

I have these few lines of code in my ASP.net app to get files from DropBox.

And I get no error but it DOES NOT WORK?  nothing happens.  This code is in an Async function

an it does get invoked correctly, etc, etc.  Folders are correct. App in DropBox is correct. My Token is correct.       Any help would be much appreciated.  Thank you.

Dim myDbClient As New DropboxClient("MyToken")
myDbClient.Files.DownloadAsync("/" + folder + "/" + fileName).ConfigureAwait(False)

Dim folder = "Mike_Lino_Taxi_App" 'dropbox folder name
Dim fileName = "lino123A.txt" 'dropbox file name

response = Await myDbClient.Files.DownloadAsync("/" + folder + "/" + fileName).ConfigureAwait(False)

Dim bytes = Await response.GetContentAsByteArrayAsync().ConfigureAwait(False)

Using fileStream = File.Create("C:\Projects\Mike\lino777.txt") ' local path
       fileStream.Write(bytes, 0, bytes.Length)
End Using

I don't see anything obviously wrong. Please step through this code with a debugger and figure out which exact line doesn’t work as expected and share the details.

Thank you for your response Greg.

This is the line that fails: 

 Dim response As IDownloadResponse(Of FileMetadata) = Await myDbClient.Files.DownloadAsync("/" + folder + "/" + fileName)

I have a Try Catch in my code and error is:  "An error occurred when send the request."

This error message is too general.  I checked all my folders, names, etc.  All looks good.  

any help would be appreciated.  Is there any way of getting more details about this error.  Can I get some trace log or something?

Thanks again.

If the Dropbox API call is failing, you should get a more specific error from the API. It sounds like you're only retrieving a generic error message though. Please inspect the exception, e.g., using the debugger, to get more information.
