Describe the bug

Nitro PR https://github.com/unjs/nitro/issues/2217 seems to have introduced a breaking change for server handlers with .json.ts suffix.

Additional context

Nuxt OG image uses those routes for example: https://github.com/nuxt-modules/og-image/issues/172 Which makes automatic dependency updates like this go nana: https://github.com/dargmuesli/creal/pull/442
