Simple Memory node common issues

Here are some common errors and issues with the Simple Memory node and steps to resolve or troubleshoot them.

Single memory instance

If you add more than one Simple Memory node to your workflow, all nodes access the same memory instance by default. Be careful when doing destructive actions that override existing memory contents, such as the override all messages operation in the Chat Memory Manager node. If you want more than one memory instance in your workflow, set different session IDs in different memory nodes.

Managing the Session ID

In most cases, the sessionId is automatically retrieved from the On Chat Message trigger. But you may run into an error with the phrase No sessionId.

If you have this error, first check the output of your Chat trigger to ensure it includes a sessionId.

If you're not using the On Chat Message trigger, you'll need to manage sessions manually.

For testing purposes, you can use a static key like my_test_session. If you use this approach, be sure to set up proper session management before publishing the workflow to avoid potential issues in a live environment.
