I can't verify the Meta webhook with the WhatsApp Trigger node

I can’t verify the Meta webhook with the WhatsApp Trigger node. It doesn’t return the challenge parameter in plain text in the GET request, only the JSON response. Version: 1.113.3, Cloud environment. Could you please check?

I created a WhatsApp stream, but no matter what I do, I can’t get it to work, even though I’ve activated the stream and set it to live mode on Facebook. I searched the forum for a similar topic, but couldn’t find one.

I need some urgent support on this issue. If there is someone who is willing to pay me to do this work, could they contact me? I need support on other similar issues as well.
