なんか何やってもe2eだけ起動してくれない

anatawa12 · 2026-04-19T05:15:32Z

endpoints/endpoints.tsと``endpoints/endpoint.ts`が循環 import になってるのでそれがなんかvitestのtransform時にいい感じに解決できていない可能性がありそうなので、それらでの直接のimportをやめてエンドポイントの実装内でのdynamic importにすると良いかもしれない

自分がendpointsのリファクタしたときに気になったけど一応動いてたので直さなかったって範囲なので、解消したほうが安定しそうだなとは思っていた
