const { Serper } = require(‘langchain/tools’);

return new Serper(‘deletedapikey’);

This code will only run and return data if an output got created which is not “Main”.

You can import LangChain and use all available functionality. Debug by using console.log() statements and viewing their output in the browser console.

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Langchain recently move around some code, and we upgraded to a newer minor version. Technically langchain should have not broken the API like this in a minor version, but unfortunately they did.

Can you please try replacing

const { Serper } = require('langchain/tools');

with

const { Serper } = require('@langchain/community/tools/serper');
``` ?
