How to write one row to Google Sheet

[SuperTempAccount]

Hey Automaers,

How can I write a single value to Google Sheets?
I'm trying to write the last value in a single-column table to a Google Sheet.

I am writing to: sheet1!C2:C2

The Google Sheet block has two options: Table for writing the whole table, or Custom for a custom JSON value.

I've selected Custom and entered this for the value.

I get the error t.forEach is not a function.

I tried including multiple values in the JSON as a test but still receive the same error.
