The payload of webhook event "chat_channel.member_invited" has empty members[0].id

The payload of chat_channel.member_invited lacks the member id which breaks our system.
We invite an internal user to the channel and then receive the webhook event chat_channel.member_invited. However, the payload lacks the most important data which is payload.object.members[0].id. The id of new participant.

We found that there are other webhook event lacking the id (contact_id in chat_message.sent).

Could you please check out the payload of all webhook events? I doubt that most of webhook event currently miss id information. Thanks
