Oh dear. @axelboc I think this is due to #1239. It also broke the HSDS demo.

Thanks for the heads-up @bmaranville

[axelboc]

Hmm weird, but I don't think it is. It was working fine; I remember using the production demo yesterday. I've checked on Netlify and the env vars are set properly. It looks like it's an issue with the Vite upgrade from this morning's PR #1245. Maybe try downgrading for now?

[loichuder]

Yup, downgrading Vite to 3.1.3 did the trick. The demo is back online

[axelboc]

They've just fixed it: vitejs/vite#10684. Just waiting for the next release now.

[axelboc]

They've released the patch, so I've upgraded to it.

Those new env var assertions are proving themselves quite useful already 😆
