So I think i was able to work around the issue... What I am doing is
passing a JSON response back to a device using the rest API, so I am
setting the header to be json. Instead of sending back a string in the
request.get_data, I used the six.ensure_binary to convert the string into
bytes and returned the bytes instead of the string, and now I'm not seeing
the error anymore. Now I'm getting a 400: bad request code back, but I
will have to troubleshoot this one further.
result = " { \"model\": { \"frames\": [{\"icon\": \"%s\", \"text\": \"WeeWx
Data\"}, { \"icon\":\"2497\", \"text\":\"%s\"}, { \"icon\":\"20768\",
\"text\":\"%s\"}, { \"icon\":\"1153\", \"text\":\"%s\"}, { \"icon\":\"72\",
\"text\":\"%s\"}, { \"icon\":\"2423\", \"text\":\"%s\"} ],\"sound\":
{\"category\":\"notifications\",\"id\":\"%s\"} } }" % (self.icon,
values['temp'], values['pressure'], values['wind speed'], values['rain
today'], values['humidity'], self.sound)
logdbg('Result: %s' % result)
result_bytes = six.ensure_binary(result)
logdbg('bResult: %s' % result_bytes)
return result_bytes
