Thank you very much, this definitely fixed my issue!
Nvm it was only to change the “Receive Message Status Updates” option to just “On fail” because Whatsapp API always send the status “Sent” and “Delivered” even tho you dont have them activated in that option. This way only if the API fails the workflow receibe the error and not the both statuses mentioned.
Hello everyone, I had the same problem and it seems to solve the problem.
thannk you very much, this was the solution for me, i made some changes and forgot to update the chatinput, i updated it and solved the problem.
worked for me too
For me this was a simple case of having a System prompt, but not a user prompt.
Adding a user prompt fixed it.
Hope this helps someone

I had the same issue, after some debugging this issue is caused when user input message is empty. It should solve when you put an input message or if user input message it not empty.
Olá, esse erro geralmente ocorre quando você tem dois dados chegando no seu node ou um valor vazio. Para resolver adicione um node Merge ou trate o dado vazio ( {{ $json.example || ‘ ND ‘ }} ).
You fix this by writing something in the Prompt (User Message) in the agent node
