Sendgrid-nodejs: deepmerge needs to be updated to latest version to prevent webpack bug

[celicoo]

Issue Summary

The current deepmerge version doesn't work with Webpack:

TypeError: merge is not a function
    at Personalization.deepMergeDynamicTemplateData (/opt/sulvo/cloudflare-app/handlers/.webpack/service/webpack:/node_modules/@sendgrid/helpers/classes/personalization.js:289:1)
...

This is a known issue.

Steps to Reproduce

1. Setup Webpack
2. Send a transactional email injecting dynamic template data, e.g:

import sgMail from '@sendgrid/mail'

sgMail.setApiKey(process.env.SENDGRID_API_KEY)

sgMail
  .send({
    to: '[email protected]',
    from: '[email protected]',
    templateId: '...',
    dynamicTemplateData: {
      name: '',
    },
  }).catch(console.error)

Technical details:

• sendgrid-nodejs version: 6.3.1
• Node.js version: 10.15.1

Thanks for bringing this to our attention @celicoo! I've added this to the backlog.

@thinkingserious any update on this?

[richardcase]

Is this going to be included in a release soon?

Hi, this is blocking sendgrid adoption for us. Any ETA on release?

[robertsmikej]

Blocking adoption for us too, please let us know what the status is. Thanks!

If currently you're using Webpack, just add this to your webpack config file (I know this is dirty, but it works!).

  resolve: {
      alias: {
        deepmerge$: 'deepmerge/dist/umd.js',
      }
  }

Note that updating to 6.5.1, which includes #935, didn't work. I had to implement the workaround by @terryds, which worked!

Also ran into this issue... giving @terryds's dirty solution a try... come on sendgrid!
