Hono Scalar failed with Vercel serverless function

I use @scalar/hono-api-reference to show an Api documentation and my stack use vercel with api directory. When I use vercel dev or in production mode, I have this error

Error: No "exports" main defined in /Users/***/Workspace/***/apps/emails/node_modules/@scalar/hono-api-reference/package.json
