UnhandledPromiseRejectionWarning: Unauthorized (401) Maximum credits exceeded

[LiubovBahatchenko]

I integrated sendGrid and everything worked fine, but now I receive the following error message below every time I try to send emails.
Although my limit was not exceeded (only 102 emails were sent this month, and a limit is 100 emails per day)

(node:2233) UnhandledPromiseRejectionWarning: Unauthorized (401)

(node:2233) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:2233) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

The following code is used to send the email:

const sgMail = require('@sendgrid/mail');
const { SENDGRID_API_KEY } = process.env;

const forgotPasswordMail = (to, first_name, last_name) => {
  sgMail.setApiKey(SENDGRID_API_KEY);
  const msg = {
    to,
    from: '[email protected]',
    subject: 'Your password reset request',
    templateId: 'd-71746df705c44a8b9d5bb5c10d861754',
    dynamic_template_data: {
      first_name,
      last_name,
    }
  };
  sgMail.send(msg);
}

Technical details:

• node version: v10.15.3
