Yowsup: AttributeError: 'NoneType' object has no attribute 'getChild'
Hi, I'm trying to use Whatsapp in my Raspberry Pi 3. The problem is when I try to send a message from my Raspberry Pi to my phone. That's the error:
pi@raspberrypi:~/yowsup $ python yowsup-cli demos --config yowsup-cli.config --send XXXXXXX "hola"
yowsup-cli v2.0.15
yowsup v2.4.102

You are sending a message to someone which hasn't wa or you put incorrectly the jid. Sync contact if you get the number out, you found the error.

I have the same issue.
This issue does NOT occur if i do /send [number] [message] in the command line client.

Make the first login with cli app to generate keys:yowsup‎-cli demos -y -d -c configfileAnd then /L
EDIT: Issue resolved, at least for me.

I tried what @jlguardi said but unsuccessful.
can anyone help me?

@DiegoVallely I've experienced this kind of exception if I send a message to somebody which isn't registered in whatsapp or his jid contains an extra number (i.e: phone 5435xxx has whatsapp jid 54935xxx@wha...)
jlguardi
on 11 Aug 2016
@jlguardi how can I know if a number has an extra number or isn't registered in whatsapp before I send message?

Sync contact info with GetSyncIqProtocolEntity

EDIT: I am stupid. I acutally used a completely wrong phone number for the message destination. The "/contatcs sync" output is terribly misleading ("Invalid Numbers" is empty). Nevertheless, I first experienced this problem upon receiving. Maybe this can happen if you receive a message from someone who managed to have their account deleted?
I face the same problem. It seems to occur as soon as I send a message to a contact I don't have the encryption keys for. As you can see in the debug output, the server actually does not send the "key" section. As a result, userNode.getChild("key") cannot possibly return a valid node. Here is the full log:

@hoehermann your edit is right. I've managed exception when no key is returned and checked for existing account.

Was someone able to fix this? Especially for the extra number? We tested sending messages to foreign numbers like dubai (+971, extra country code number and also longer numbers dan in the netherlands +31) and it returns AttributeError: ‘NoneType’ object has no attribute ‘getChild’ and crashes the application.
