Contact form with SendGrid

OK. I fixed a few things that were wrong and changed my back end function to handle a sender address as well as a recipient address being passed (sendgrid.js remained the same). I’m still not getting any emai l going through. I even generated a new API-Key at SendGrid, but that didn’t help either.

Back end:

//email.jsw
export function sendEmailWithRecipientAndSender(subject, body, recipient, sender) {
  const key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
  return sendWithService(key, sender, recipient, subject, body);
}

On the page:

// libraries that we need
import wixData from 'wix-data'; // Used to query database
import wixUsers from 'wix-users'; // Used to get the current user
import {sendEmailWithRecipientAndSender} from 'backend/email';

// ...Left out function here that fills read only fields...

// Check that they don't have empty subject and message and send
export function button1_click() {
	if (($w('#input3').value !== "") && ($w('#textBox1').value !== "")){
		sendMsgData; 
		$w('#input3').value = "";
		$w('#textBox1').value = "Message Sent";
	}
	else{
		$w('#input3').value = "Subject Required!";
		$w('#textBox1').value = "Message Required!";
	}
	
}

function sendMsgData() {
     let user = wixUsers.currentUser;
     let userId = user.id;
     wixData.query("Test")
    .eq('_id', userId)
    .find()
    .then( (results) => {
          const sender = results.items[0].email;
   	  const recipient = results.items[0].sendEmail;
   	  const subject = `New Mesage from ${$w("#input3").value}`;
   	  const body = `Name: ${$w("#input1").value}
    	\rEmail: ${$w("#input2").value}
    	\rMessage: ${$w("#textBox1").value}`;    	
    sendEmailWithRecipientAndSender(subject, body, recipient, sender)
    .then(response => console.log(response)); 
 });
}

I tested to make sure that I indeed had values in the parameters that I was passing. I did, and they look valid. Is there something inherently wrong in how I am “calling” SendGrid?
