Response body

Webhook error: Cannot read properties of undefined (reading 'contentType')

System information

medusa-plugin-contentful: 1.2.4 @medusajs/medusa: 1.7.3 Node.js version: 17.1.0 Database: postgres Operating system: Docker version

Steps to reproduce the behavior

I've followed this guide: https://www.contentful.com/blog/create-a-composable-commerce-site-with-contentful-and-medusa/

The sync from Medusa to Contentful works.

Though the sync back to medusa, using Contentful hooks fails.

Expected behavior

After editing a product in Contentful see the changes synced to Medusa.

Additional context

Two locales are active in Contentful:

• en
• nl

Well, after a bit of digging I realized that the problem comes from Contentful which changed the default content type. You have to set it manually.

@Baldrani Thanks for pitching in. We'll make sure to add a note in our documentation :)
