Netlify Image CDN not working with Gatsby and Contentful plugin

Hi,

I’m trying to implement Netlify Image CDN on a Gatsby site using Contentful as the CMS, but so far, all images are still being served through Contentful’s CDN.

I’ve set the environment variable NETLIFY_IMAGE_CDN to true. I’ve added the remote_images property to the netlify.toml file. I’ve updated Gatsby, gatsby-adapter-netlify, and all other Gatsby plugins to their latest versions. I’ve also enabled the imageCDN option of the adapter in the Gatsby config.

What am I missing?

Here is my branch deploy: https://migrate-to-gatsby-v5--ace-hotel.netlify.app

And here is my netlify.toml file:

[build]
  command = "gatsby build --log-pages"
  publish = "public"

[build.environment]
  NETLIFY_IMAGE_CDN = "true"

[images]
  remote_images = ["https://images.ctfassets.net/guen72jxl4tk/.*"]

[[redirects]]
  from = "https://www.sighor.fr/*"
  to = "https://www.ace-hotel.com/"
  status = 302

[[redirects]]
  from = "/"
  to = "/en/"
  status = 302
  conditions = {Language = ["en"]}

[[redirects]]
  from = "/"
  to = "/fr/"

[[redirects]]
  from = "/:lang/:parent/:slug"
  to = "/:lang/:parent/"

[[redirects]]
  from = "/:lang/*"
  to = "/:lang/404/"
  status = 404

[[headers]]
  for = "/*"
    [headers.values]
    Access-Control-Allow-Origin = "*"

Thanks in advance!

hey @tomtuv thanks for reaching out, and apologies for the delay here! I’ve escalated this internally as I’m also seeing some potential inconsistencies in the image transformations here - we’ll follow up again on this thread as soon as we have more info to share!

Hello! I wanted to follow up on this thread to note that this is still on our engineering team’s board for review, however we’ve had to prioritize other more urgent bug fixes and improvements and don’t yet have an ETA for when this work will be completed. We’ll continue to follow up on this thread with any additional updates on progress.
