Encoding Error: Not well formed for server.ticket.putAttachment()

[anonymous]

The error: <Fault -32700: 'not well-formed (invalid token): line 15, column 15'> occurs when putAttachment() is used.

# Read file and write to Trac
ticketNum = 97
imageFile = "Tick_97_TracAttach_0_.png"
with open(imageFile, "rb") as image:
    data = image.read()
fileName = p.ticket.putAttachment(ticketNum, imageFile, "Image from D2D", data, True)

There are no problems with the getAttachment() function

You can't put raw binary data into an XML stream. It is bound to cause errors when parsing.

The spec says that the data is Binary, and in this case that means xmlrpclib.Binary type:

from xmlrpclib import Binary
...
    data = Binary(image.read())
...
