Update the Kinsta Must Use plugins when deploying with Trellis

Hi, I’m using Trellis to deploy my site to Kinsta and it works flawlessly apart from one part. I can’t seem to get it to download the latest version of Kinsta’s required plugins. My composer.json file has the correct entry in repositories:


    {
      "type": "package",
      "package": {
        "name": "kinsta/kinsta-mu-plugins",
        "type": "wordpress-muplugin",
        "version": "3.4.0",
        "dist": {
          "url": "https://kinsta.com/kinsta-tools/kinsta-mu-plugins.zip",
          "type": "zip"
        }
      }
    }

As per the Composer docs, the correct way to update a type: package entry like this is to manually bump the version number. When I clear my composer cache and run composer update, it correctly updates composer.lock and grabs a fresh copy of the zip from the server (it doesn’t actually know what version it is, it just assumes it’s new because the version number changed).

Then I commit & push composer.lock to my staging branch, and run trellis deploy staging site.com. I can see composer.lock is updated on my staging site, but the Kinsta MU plugin files have not changed.

Why would it work locally but not during the deploy command? Am I missing something?

I’ve asked Kinsta Support but the answer is unclear. ChatGPT suggested I delete the old files before deploying but that might break the site. Thanks for your help!
