Describe the problem/error/question
I’m running into an issue with my workflow when trying to load messages from the last session. The request I send to the webhook returns the following error:
{“code”:0,“message”:“Workflow Webhook Error: Workflow could not be started!”}
I followed the documentation closely:
-
Selected From Memory in the Chat Trigger node.
-
Set SessionId to Connected Chat Trigger Node in my Postgres Chat Memory node.
-
Used the same Postgres Chat Memory node for both the Chat Trigger and the Agent.
Since it didn’t work, I looked for similar issues in the community. I found only one user with the same problem, and they solved it by using two separate memory nodes — one for the Agent and another for the Chat Trigger — but I still couldn’t get it to work.
Has anyone encountered this issue before or found another solution?
I send the following request to my weebhook url:
Method: POST
Body: {
“action”: “loadPreviousSession”,
“sessionId”: “7a4e3dd9-e329-4556-a2f9-30f02c61f7be”,
“metadata”: {
….. some metadata …..
}
}
Then I get the following response:
{
“code”: 0,
“message”: “Workflow Webhook Error: Workflow could not be started!”
}
In my workflow, the execution shows this error:

- nodeJsVersion: 22.21.0
- nodeEnv: production
