I am trying to automatically post some numbers to my slack channel via the slacker package (version 0.8.6). Sometimes the number that needs to be printed is a 0, but I've found that posting 0 or "0" gives me an error...
from slacker import Slacker
API_TOKEN = XXXXXXXXXX # I load in my api token from an environment variable
slack = Slacker(API_TOKEN)
channel = '#test-channel'
message = "0"
slack.chat.post_message(channel, message, parse='full')
I get this error: slacker.Error: no_text
Is this a bug in my code, slacker, or the Slack API itself?
Full stack trace:

I reproduced your problem. I'm looking at Slacker and it seems like the Slack API is returning the error with that message.
try: message = '0\n' (It's a silly hack! But nothing else worked)
the Slack Desktop App seems to render it as if you'd sent 0
