Issue with webhook triggering on document creation in

Webhooks and delta-functions
I'm trying to write a webhook that fires whenever a field in a document gets new information. In my mind, that should happen when a document is created, the field in question is updated, and when the document is deleted.

However, when I set the "filter" field of my webhook to look like this:

_type == "someType" && delta::changedAny(someField)
(and mark my webhook to run on both creation, updating and deleting)

The webhook doesn't trigger on creation. I think it should. Am I doing something wrong, or is this the intended behavior?

I’ll ask the Content Lake team if that’s the expected behaviour. It may end up that you need to use the following, but I’ll confirm:

_type == "someType" && delta::changedAny(someField) || before().someField == null)

That would work for the creation use case, but not for the deletion usecase.

. The team got back to me that the
functions weren’t intended for create/delete cases, and therefore behaviour is not guaranteed. They’ve suggested going with this approach:

_type == "someType" && delta::changedAny(someField) || delta::operation() == "create" || delta::operation() == "delete"

Alright I’ll see if that works in my usecase
