```

Using the `DCC receive` example with modified code:

```py
def on_welcome(self, connection, event):
self.connection.privmsg("NickServ", "IDENTIFY ")
self.connection.join("#THE.SOURCE.NOSPAM")

def on_privmsg(self, connection, event):
self.connection.privmsg("TS-APP|US|P|39503", "xdcc send #169")
```

Start with the DCC receive example and the CTCP handling path shown in the traceback. Compare the parser's expected fields with the DCC SEND message in the report, then check existing DCC-related tests or examples. Done means a valid DCC SEND request is handled without the reported ValueError.
