I suggest adding event.kind: pipeline_error in case of pipeline failure, I see this behavior adopted more and more.

We should consider using error.message as an array, as it has become increasingly common but optional.

[zmoog]

What about also setting event.kind?

Here's an example of the current trend: https://github.com/elastic/integrations/pull/7043/files#diff-ff596a529bb3558054ae525d4e233a54a30963b2ac998fc37eeaa1ed29d66474
