"some difficulties when using make.com to create an integration between LINE and ChatGPT

I encountered some difficulties when using make.com to create an integration between LINE and ChatGPT. In the part where LINE sends a reply token, I can’t find the option for contents text.value in the message.

I think it might be due to more fundamental operational errors on my part, so I reapplied for my Chat GPT API and regenerated the webhook for my LINE official account, but the problem still hasn’t been resolved.

Why can’t I find ‘content text.value’ in the text field when sending a reply message? If this cannot be found, GPT won’t be able to send the reply message back to my LINE.
