Error when building chat UI space with default config HF

[lccnl]

Hello, I have a space that used to work until yesterday, it is created with the standard chat-ui docker image. Since today when it is built, I have the following error:

--> RUN npm run build

> chat-ui@0.6.0 build
> vite build

"BaseClient" and "TokenSet" are imported from external module "openid-client" but never used in "src/lib/server/auth.ts".

Any clue? Thanks!

Hi! i broke backwards compatibility with the latest change by accident, working on a fix.

If you want a quickfix for your space, feel free to look at this PR for a similar fix. (just add 'type' : 'tgi' in your endpoint definition)
