Flatmap error

Hey I got this error from gemininot and I don’t how to solve it. It happens once and then doesn’t. I tried to use “.to JOSN string” to avoid this but doesn’t work, I asked AI and it suggested use “.join “\n””, Any ideas?

Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

Share the output returned by the last node

It’s an expression error inside one of your parameters. Could you SS the parameters section of your node instead?

Already shared the 2 nodes, do you mean something else?
