/functions/_middleware.ts file, but I'm not sure where they should be. I have the attached build configuration, but should I create the functions directory in /, /frontend, or /frontend/build?npx wrangler pages dev build (running in /frontend and after npm run building manually) seems to find the _middleware.ts file in /frontend/functions because it fails to build if I don't have the plugin npm installed.data-static-form-name and its method/action attributes has not been overwritten.
