URLSearchParams Error with Outgoing Webhooks

Description:

When trying to convert JSON to application/x-www-form-urlencoded with URLSearchParams in an Outgoing Web Hook.

I'm trying to use RocketChat outgoing webhook with Twilio SMS API

Here's my snippet of Outgoing Webhook

let newBody = new URLSearchParams({
    // From and To are E.164 phone number format
    'From' : '',
    'To' : '',
    'Body': text = request.data.text
})

Steps to reproduce:

Create an Outgoing Webhook
Create JSON array
Try to use URLSearchParams to convert to urlencoded capable string
Try to trigger Outgoing Webhook
Receive error in Logs

Expected behavior:

I'm expecting the Outoing Webhook to work.

Actual behavior:

I receive the error below

Additional context

Per this article, the workaround is to use encodeURIComponent. So, I'm not sure if URLSearchParams is supposed to be there.

var details = {
    // From and To are E.164 phone number format
    'From' : '',
    'To' :'+1' + number,
    'Body': text[1]
};

var message = [];
for (var property in details) {
    var encodedKey = encodeURIComponent(property);
    var encodedValue = encodeURIComponent(details[property]);
    message.push(encodedKey + "=" + encodedValue);
}
message = message.join("&");
