[BUG] Webhook configured, enabled but not working

[eroji]

Describe the bug
I installed BotKube on my cluster that's running k8s 1.21.5. I have it configured to send Slack and webhook notifications. However, the webhook portion does not work. The receiving endpoint never got anything from BotKube.

To Reproduce
Steps to reproduce the behavior:

1. Install BotKube 0.12.4 via deploy-all-in-one.yaml
2. Change configmap accordingly
3. Update the secrets configuration
4. Make a change to a deployment in the monitored namespace

Expected behavior
There should be a webhook call triggered, but nothing was received

Additional context
Here is my config

Hi @eroji, could you please see the logs from the BotKube container?
A few days ago I tested webhook configuration and it worked fine, however I used the latest image from develop.

To confirm you encounter an issue on BotKube side, you can try to follow the guide https://www.botkube.io/contribute/webhook-develop/ and configure BotKube with sample web server which handles incoming requests.

I just looked at the botkube pod, but it's overwhelmed with Slack unmarshalling errors since I have Slack configured. The deployment changes does create Slack notifications however, but not webhook calls.

I will try the echo-server you suggested.

Right, the issue with Slack unmarshall errors when using Huddles is resolved in #579 and will be followed-up with #619. If the echo-server will work for you, please try to look for errors specific for the outgoing webhook integration.

Thank you!

Hey @eroji, any news regarding your issue? Have you been able to test webhook integration with the echo server?
