UNSUPPORTED_CHAT_OPERATION

What happened

The chat cannot do what you asked. Examples are a threaded reply in an SMS chat, or a group action on a group that is not an established iMessage group.

How to fix it

Check the chat’s capabilities with GET /v1/chats/{chat_id} and the feature guide for where the operation is supported.
