Once you have called read() on a file subsequent calls will not yield any data. The first call to read() reads the entire buffer and there will not be anything left when you call it again

    print(type(request.FILES["file"].read())) # This line has read the entire buffer
    imageFile = request.FILES["file"]
    receipt_image = imageFile.read() # There is nothing left to read so this returns b''
