How to post-process LL Chain response?

[dortiz42]

Hi,

I'm new to using Flowise.
I want to process the response returned by the "LL Chain" node. I'm trying to do this with a "Custom JS Function" node, but I get the following error:

`2025-01-15 15:17:39 [DEBUG]: [server]: Initializing Custom JS Function (customFunction_0)

2025-01-15 15:17:39 [DEBUG]: [server]: Finished initializing Custom JS Function (customFunction_0)

at async createInternalPrediction (C:\Users\ºº\AppData\Roaming\npm\node_modules\flowise\dist\controllers\internal-predictions\index.js:14:33)`

The "Custom JS Function" node takes input from the output of the "LL Chain":

Am I doing something wrong?
If this is not the correct way, how could I process the response from the "LL Chain" node?

Thank you very much.
