Memory node error

Questions
1

Hi everyone,

n8n noob here, just trying out my first workflow.

In short, I’m looking to make a workflow that scrapes Reddit posts & comments, then feeds that data to an AI Agent that can process it and suggest discussions that align with our business, and in which we can contribute.

I’m getting this error:

“input values have 3 keys, you must specify an input key or pass only 1 key as input”

Does anyone know a fix for this? Both ChatGPT and Claude have been useless.

Thanks in advance
