How to create 404 page for SSR single blog post?

Hi Priyanka,

It doesn't feel right that a getByUID call with an unexisting uid trigger a 'api_parsing_error' error.
I usually expect a null document or a better error :confused:

ParsingError: [function at(..)] unexpected field 'my.page.uid' on line:1 col:6 in query '[[at(my.page.uid, "guide")]]'
[[at(my.page.uid, "guide")]]
     ^

  response: {

    message: `[function at(..)] unexpected field 'my.page.uid' on line:1 col:6 in query '[[at(my.page.uid, "guide")]]'\n` +

      '     ^\n',
    pos: { line: 1, column: 6, id: 1, location: 'query' }
  }

Is-it plan to improve things about it? Thanks
