Production server fails with file not found error

[david-pfx]

The error is:
Error: ENOENT: no such file or directory, stat 'D:\MyDocs\dev\Evolutility\evolutility-ui-react\src\public\index.html*.css'

Apparently caused by having moved the server.js. Changes required:

res.sendFile(path.join(__dirname, '../public', 'index.html'))

Also

app.use(express.static(path.join(__dirname, '../public')))
