[BUG] Botkube failed to send webhook with error code of 400

[canberkkoc]

Describe the bug I install bot kube with helm and take this error on pod logs "Error Posting Webhook: 400". I tried on other pods at the same cluster webhook is working.

To Reproduce

1. Install botkube with helm like this command: helm install botkube --namespace botkube
   --set communications.webhook.enabled=true
   --set communications.webhook.url='xxxxxxxx'
   --set config.settings.clustername=xxxxxxxx
   infracloudio/botkube
2. Check logs with kubectl command.

Expected behavior Send alert to my slack channel via webhook.

@canberkkoc could you please let me know which platform you are using? Is it Slack/Teams webhook or some other platform.

@PrasadG193 : I too face the same issue. I am on EKS 1.21 - Slack Integration using Webhook. With debug enabled, I got the below error.:

Hi I got the same 400 error when using google chat web hook. I have used the following installation command

helm install --version v0.12.3 botkube --namespace botkube \ --set communications.webhook.enabled=true \ --set communications.webhook.url="https://chat.googleapis.com/v1/spaces/********" \ --set config.settings.clustername=docker-desktop-test\ --set image.repository=infracloudio/botkube \ --set image.tag=v0.12.3 \ infracloudio/botkube

Hi, is there any fix?

Hello everyone, This is not really an error for the webhook integration. Status code were returned directly from the target system, so in this case (status code 400 - "Bad request") the target system (Google Chat, Webex) indicated it couldn't handle the request. That means, you would need an adapter which converts the Botkube outgoing webhook payload to the one you want to integrate with.

This is how the payload is defined on Botkube side: https://github.com/kubeshop/botkube/blob/main/pkg/sink/webhook.go#L33

Hope that helps. Cheers!
