VB.NET File upload using WebApi: UnExpected end of MIME - vb.net

Question

Everything seems to be working except I get this below error in the WEBAPI:
Unexpected end of MIME multipart stream. MIME multipart message is not complete.
When I upload the same file from postman to the WEBAPI endpoint it works perfectly. Makes me think its a problem with the VB application.
BTW: Not skilled in VB (Inherited Application trying to make it work to upload large files)
Dim fileBytes As Byte() = Nothing
Dim boundary As String = "---------------------------" + DateTime.Now.Ticks.ToString("x")
Using binaryReader As New BinaryReader(fileUpload1.PostedFile.InputStream)
fileBytes = binaryReader.ReadBytes(binaryReader.BaseStream.Length)
binaryReader.Close()
End Using
Dim request As HttpWebRequest =
WebRequest.Create("http://mylocalhost/api/directory")
request.Method = "POST"
request.ContentType = "multipart/form-data; boundary = " + boundary
request.ContentLength = fileBytes.Length
request.Accept = "*/*"
request.AutomaticDecompression = DecompressionMethods.GZip
request.KeepAlive = True
Dim newStream As IO.Stream = request.GetRequestStream()
newStream.Write(fileBytes, 0, fileBytes.Length)
'newStream.Close()
Dim response As WebResponse = request.GetResponse()
' Display the status.
Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)
' Get the stream containing content returned by the server.
Dim dataStream As IO.Stream = response.GetResponseStream()
' Open the stream using a StreamReader for easy access.
Dim reader As New StreamReader(dataStream)
' Read the content.
Dim responseFromServer As String = reader.ReadToEnd()
Debug.WriteLine("File uploaded")
Return True````
