Connect "Simple Memory" to "WhatsApp Trigger" error

[Mohamed_Necib2]

Hello,

Despite looking online I could not find a solution for the error below:

Error in sub-node ‘Simple Memory‘

connect “Simple Memory” to “WhatsApp Trigger”

The problem occurs in the AI agent.

Does anyone have a clue of the reason of this error ?

Thank you for your help

try this for your AI Agent on the prompt (user message)
{{ $node["WhatsApp Trigger"].json.messages[0].text.body }}

and try this on your simple memory Key value

{{ $node["WhatsApp Trigger"].json.metadata.phone_number_id }}

because i think the error is caused by how you call this 2 value

Thank you for your help.
I try this and it worked: {{ $(“WhatsApp Trigger”).item.json.contacts[0].wa_id }}

What I do not understand is why while I copye and paste the item path : {{ $item(“0”).$node[“WhatsApp Trigger”].json[“contacts”][“0”][“wa_id”] }}

It display the error where as I can see the ID

Do you have any idea ?

how do you copy and paste it? i usually just drag and drop the field that i want and it usually automatically be filled with something like this

{{ $(“WhatsApp Trigger”).item.json.contacts[0].wa_id }}

and if you can, to mark my answer as the solution as it would greatly help the community
