Webhook does not appear to be set

On start it seems to be setting the webhook URL. However, when sending messages to the bot, nothing gets posted to the webhook and pending updates keeps increasing.

Telegram Bot <BOT_NAME> setting webhook [ https://<URL>/users/telegram-webhook/<BOT_TOKEN>/ ] max connections:40 allowed updates:['ALL'] **pending updates:8** : True

When I manually access the webhook URL I can see that it's working as I get a {} response and I see an entry in the webserver logs. But I don't see anything if I send a message via Telegram and I do not see any line entry in the webserver logs at all as well.
