hey, @yusukebe are you still working on this? because there is a problem with drizzle drizzle-team/drizzle-orm#4249.

[yusukebe]

Hey @emersonlaurentino

If version 8 of Zod to OpenAPI which supports Zod v4 has been released, we can release this.

Before that, please use the beta:

npm i @hono/zod-openapi@beta

[emersonlaurentino]

it's working for me, thanks!
