How do I write values to a google spreadsheets row with the api?

Question

I want, in node.js, for my command to, on the second row of my spreadsheet, set the values of A-D to 1-4. The code below seems to be how the documentation wants me to do it, but I keep getting the following error:

"GaxiosError: Invalid JSON payload received. Unknown name "majorDimension": Cannot bind query parameter. Field 'majorDimension' could not be found in request message. Invalid JSON payload received. Unknown name "values": Cannot bind query parameter. Field 'values' could not be found in request message."

const {google} = require("googleapis")
const auth = new google.auth.GoogleAuth({
      keyFile: "sheets-credentials.json",
      scopes: "https://www.googleapis.com/auth/spreadsheets",
});
const client = await auth.getClient();
const googleSheets = google.sheets({ version: "v4", auth: client });
const spreadsheetId = "anidthisis";
await googleSheets.spreadsheets.values.append({
      auth,
      spreadsheetId,        
      "range": "Sheet1!A2:D2",
      "majorDimension": "ROWS",
      "values": [
          ["1", "2", "3", "4"],
       ],
});
