I have experienced this issue for more than one of my ember apps now, failing to build, resulting in the error:

TextEncoder is not defined

It probably has more to do with using an Outdated NodeJS version pinned to version 10, for build images: ReferenceError: TextEncoder is not defined · Issue #235 · jsdom/whatwg-url · GitHub

I have now updated an app to embroider, ember 4, but the deployments will fail as long as the build images use Node 10. Note that LTS is 16.17.0. How can Netlify users build ember apps with build images set to use Node version 10?

(One idea might involve pinning a fork of whatwg-url to the dependencies of the package.json, but that seems like a hacky solution to me).

Hi @srger, you can update the node version by setting an env variable or adding a .node-version or .nvmrc file. Docs: Manage build dependencies | Netlify Docs

That should allow you to set the node version to your desired node version to fix the issue. Mind trying that and reporting back?

Thanks; that worked.

Added an .nvmrc file to the base directory with simply the node version from node --version (so v18.8.0 at the time of this writing).
