ember-cli-babel 7.21.0 build/test error

Dependabot recently raised a PR on one of my repo with a version bump from 7.20.5 to 7.21.0. I have Github actions set up to run tests using the ember t command and deploy to netlify after build using the npm run build command.

The following is the error I see.

- stack: SyntaxError: /home/runner/work/abhilashlr.in/abhilashlr.in/packages/frontend/abhilashlr/components/footer.js: 
... ... as a bare identifier (This is an error on an internal node. Probably an internal error.)

The error is part of https://abhilashlr.in/ 's footer at the bottom.

I tried doing a prod build using ember b --prod and tried running a server ember s --prod and also ran tests ember t. All of these seemed to pass in local but strangely Github Actions seemed to fail.

Node: 12.x in local and Github actions

This is still very much a problem. Basically emojis cannot be used in templates. Any update on this?

Huh, this is wild 🤔. I’m not sure what would have changed in those versions that would have changed how emoji was handled within colocated templates…

I have to guess the issue is from changes upstream (in Babel itself), but we’d need to isolate those changes and figure out a path forward…
