Chat AI agent cannot be active

Describe the problem/error/question.
I want to activate my AI agent so other people can use it. However, it cannot be activated, and the Window Buffer Memory keeps popping out an error message.

What is the error message (if any)?

  1. Error in sub-node ‘Window Buffer Memory‘ No session ID found

{
“errorMessage”: “No session ID found”,
“errorDescription”: “Expected to find the session ID in an input field called ‘sessionId’ (this is what the chat trigger node outputs). To use something else, change the ‘Session ID’ parameter”,
“errorDetails”: {},
“n8nDetails”: {
“itemIndex”: 0,
“time”: “23/10/2024, 12:40:28”,
“n8nVersion”: “1.64.1 (Cloud)”,
“binaryDataMode”: “filesystem”,
“cause”: {
“level”: “error”,
“tags”: {}
}
}
}

Hi @Hunter_Yen

Thanks for posting here and welcome to the community! :partying_face:

Can you share your workflow so we can see how you’ve configured the nodes and which agent you are using.

Also, can you check that you have the latest node version of the Window Buffer Memory node (check the settings tab at the bottom).

Tip for sharing your workflow in the forum

Pasting your n8n workflow


Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```

Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
