Why am I unable to send KakaoTalk Brandmessage button messages?

If you get the following error from Conversation API:

"description": "The underlying channel reported: Button name/mobile link (linkMo) is required for free button-type templates. If template have a WL(webLink), must input linkMo"

For the best practice, please also include the Weblink in the button when creating the template.
