With the build failure, this is now definitely a problem for next week. We were already due for an update from the upstream initializr ui, now we might have to revisit the reverse-proxy situation too if this isn't solved by bumping deps:

Build is still broken

Preview link: https://initializr-web-pr-143.azurewebsites.net

• Your changes have been deployed to the preview site. The preview site will update as you add more commits to this branch.
• The preview link is shareable, but will be deleted when the pull request is merged or closed.

Need to pair with a custom InitializrService address?

A team member can use this az CLI command, replacing and for valid numbers:

az webapp config appsettings set --resource-group steeltoe --name initializr-web --slot pr-<this-PR-number> --settings "INITIALIZR_SERVICE_HOST=initializr-service-pr-<other-pr-number>.azurewebsites.net" "INITIALIZR_SERVICE_URI=https://initializr-service-pr-<other-pr-number>.azurewebsites.net/api/"

I can't oversee the impact of the changed files, but the preview site works. Building and running locally works too, so I'm good with this.
