Hi @dirkdebruin thank you for opening this issue!

It seems that you are trying to use the Event Source feature directly without using any event handler resolver, which is ok.

However, I need to understand more about which event source are you connecting this Lambda handler to.

Can you please clear this up for me? Alternatively you could also paste the input payload (redact any unwanted info) that is being passed to the Lambda handler? Thank you!
