Sendgrid-nodejs: 400 BadRequest: x-no-cors-reason

[SeanOThomas]

Issue Summary

I have a Firebase cloud function called needCode that sends an email using sendgrid. However, I always get a Bad Request.

Steps to Reproduce

1. Invoke needCode cloud function
2. Check needCode error log in Firebase console

Code Snippet

import * as sgMail from '@sendgrid/mail'
sgMail.setApiKey(SENDGRID_API_KEY);
export const needCode = functions.https.onCall((data, context) => {
    const { email, name, message } = data
    return new Promise(function (resolve, reject) {
        const msg = {
            to: '[email protected]',
            from: email,
            templateId: 'd-ac6fdd2f3ee746fc94d211ad947a8d0e',
            dynamic_template_data: {
                name: name,
                message: message
            }
        }
        return sgMail.send(msg)
            .then(() => {
                resolve(
                    { message: "Email sent" }
                );
            }).catch(error => {
                console.log(error)
                reject(
                    new HttpsError('unknown', 'Error sending email')
                );
            });
    });
})

Probably need a paid firebase account to allow external network calls. Recommend checking the error details:

console.log(error.response.body)

I have the exact same issue and error, same setup. Has anyone got a solution?

I have some other projects using the exact same setup and they don't seem to have an issue.

@teanz Have you tried my comment above?

Since the others haven't responded, I'll chime in that I found my way here with the same error and what childish-sambino suggested worked perfectly. The error messages in the HTTP response are actually really good. In my case I had a trailing space on my template ID. Just to be thorough, here is the full code snippet that solved this problem for me:

sgMail.send(msg).catch(err => {
            console.log(err);
            console.log(err.response.body)
          });;

I've updated the docs in a few places to better indicate how to handle/log error responses: https://github.com/sendgrid/sendgrid-nodejs/commit/0e8c2761fb8d0beeac8107d0d963bb6ab80b0a6d

Thanks, logging the error out further gave me the real cause... not having my sender identity setup -_- Appreciate the help.
