"google_sheets_append_spreadsheet" failed

I'm trying to use the Agent step's Google Sheets tool to add a row to a spreadsheet. I've connected to the correct sheet, but the data is not being added. The tool call fails.

The tool attempts to add the data (name, street address, town, postcode, email) as a string, but it should be added as a JSON array by the tool.

See screenshots.
