Function SendGrid Node Import error

Posted on October 18, 2023

Hi there,

I’m trying to create a function using NodeJs and SendGrid. I think I have the code correct, however, I’m getting an error on importing the SendGrid module.

Error [ERR_MODULE_NOT_FOUND]: Cannot find package ‘@sendgrid/mail’ imported from /tmp/index.mjs

Done the usual Googling and searching the community, but I can’t seem to find the solution.

Bring the import like this:

import * as sgMail from '@sendgrid/mail';

package.json looks like this:

{
  "name": "sendgrid-sendemail-js-do",
  "type": "module",
  "main": "main.js",
  "dependencies": {
    "@sendgrid/mail": "^7.7.0",
    "axios": "^1.5.1"
  }
}

Managed to successfully get a different function working after working through issue, but this one seems to be wracking my brains!

Any pointers would be appreciated.

Hi there!

This indeed should work as expected. Do you have your package-lock.json also added to your GitHub repository?

Here is a quick demo app that includes some extra Node dependencies that you could use as a blueprint:

You can also try using the --remote-build flag. When you run doctl serverless deploy with the --remote-build flag, the Functions service performs a remote build. The remote build uses the toolchains present in the runtime container for the chosen language.

Best,

Bobby
