Sendgrid-nodejs: deepMergeDynamicTemplateData

поместив это в обработчик функций netlify для лямбда

// For more info, check https://www.netlify.com/docs/functions/#javascript-lambda-functions
export function handler(event, context, callback) {
  console.log('sending')
  console.log(event)
  console.log(context)

  const sgMail = require('@sendgrid/mail')
  sgMail.setApiKey(process.env.SENDGRID_API_KEY)
  const msg = {
    to: '[email protected]',
    from: '[email protected]',
    templateId: '#ID',
    dynamic_template_data: {
      recipient: 'alex',
    },
  }
  sgMail.send(msg).catch(function(error) {
    console.log(error)
  })
  console.log('sent sign up')
}

Я получаю следующее
