In what case will updateMessageInteractionInfo's `interaction_info` be null?

[vincentneo]

I realised today after triggering removeMessageReaction on a message that:

• has 0 view count
• has 0 forward count
• has no other reactions other than the one being removed
• has no reply info

that the subsequent updateMessageInteractionInfo contains just the message_id and chat_id without interaction_info.

Does that mean that it is safe to assume that that only happens on the exact scenario in cases such as mentioned above?

Thanks.

It is null if message doesn't have interactions. Currently, it means view_count == 0, forward_count == 0, reply_info == null and no reactions.

got it, thanks!
