ssg fails if _error.tsx exists

[sho-hata]

What version of HonoX are you using?

0.1.26

What steps can reproduce the bug?

1. npm create hono@latest
2. choose template: x-basic
3. Change vite.config.ts as in https://github.com/honojs/honox?tab=readme-ov-file#ssg---static-site-generation
4. bun run build

What is the expected behavior?

index.html is output to dist/.

dist
├── .vite
├── articles
├── static
├── _routes.json
├── _worker.js
├── favicon.ico
└── index.html

What do you see instead?

index.html is not output to dist/. No error message will be displayed.

dist
├── .vite
├── articles
├── static
├── _routes.json
├── _worker.js
└── favicon.ico

Additional information

• If you delete error.tsx, ssg build is successfully performed and index.html is generated
• The _error.tsx file generated by the honox template is treated as a special file in hono because it's used for creating custom error handlers.
  

  honox/src/server/server.ts

  Line 192 in 034cd20

  const errorHandler = getErrorHandler(dir, errorMap)

  
  I suspect that this might be affecting the SSG build process.

Maybe it has something to do with this issue: #234
