Sentinel event not triggered

Hi,

I was looking into an issue we had on our system and traced it back to an event not being triggered by the sentinel.

The transaction hash is this one:

0x6ef82b1d398c697255751cd13a8e6b5d863aa812928ff84334be822f9d3008e3

The tenant id is:

5b58017d-d307-4e53-8d5d-d7e8cc8a0415

The sentinel id:

c33b2f90-4ef8-431a-8ce3-74e01a83088b

Our whole implementation was built about this being solid.

What's the reason for this webhook not being triggered?

Is there a retry policy?

What's the best practice here?

Thanks,

Jonathan
