[BUG] Error Posting Webhook: Ɛ

[Timvissers]

Describe the bug
When sending job events to (slack) webhook, the following occurs.
We are using v0.9.1 on AKS 1.16.
I tested this with different webhooks. The webhooks work for other purposes, eg when using the same webhook config in kubewatch, it works.

To Reproduce
Configuration:

logLevel: debug
config:
  resources:
    - name: job
      namespaces:
        include:
          - all
        ignore:
          -
      events:
        - create
        - update
  communications:
    webhook:
      enabled: true
      url: https://hooks.slack.com/services/<redacted>
  settings:
    upgradeNotifier: false

Start a job

Expected behavior
The job should be posted to the webhook without error

UPDATE:
It works correctly when using https://bin.webhookrelay.com/...
So it must be somehow related to our slack webhook. (we don't need a slack webhook, I just use it to test)

Hi @Timvissers, can we close this issue, I hope it is not a problem anymore.
