i'll move this convo here: for reference: https://sanity-io-land.slack.com/archives/C9Z7RC3V1/p1712014795716969
in short though it looks like when i extract the schema it looks like it might be ignoring the required validation field? or im misunderstanding the reason i get 
pageData: _PageData_ | _null_;
on a field that is required

What's the output of 
sanity schema extract --enforce-required-fields
, just tested it locally and it worked 🤔

so here is my groq

    const getPageData = groq`*[_type in ['product', 'page', 'blogPost'] && pageData.slug.current == $slug][0]{
    _type == 'product' => {
      ...,
      pageData
    },
    _type == 'page' => {
      ...,
      pageData,
      
    },
    _type == 'blogPost' => {
      ...,
      pageData
    }
  }`;

    const pageData = await client.fetch<GetPageDataResult>(getPageData, {
      slug,
    });
and here is the full type


export type GetPageDataResult = {
  _id: string;
  _type: "blogPost";

  _updatedAt: string;
  _rev: string;
  pageData: PageData | null;

oh, wait. Mixing bugs/discussions here!
Apr 2, 2024, 4:21 PM
You need to run 
sanity schema extract
with the 
--enforce-required-fields
flag, then you can run 
sanity typegen generate
Apr 2, 2024, 4:21 PM
ah let me give that a go, might need to clear that up in the docs, unless i read them wrong (which is a possibility lol)
Apr 2, 2024, 4:22 PM
oh, the docs are wrong! I'll get that sorted
Apr 2, 2024, 4:22 PM
yup, that fixed it and makes more sense now
Apr 2, 2024, 4:23 PM
i was wondering if i misunderstood how the schema was working lol
Apr 2, 2024, 4:23 PM
seemed weird that field was set as optional
Apr 2, 2024, 4:24 PM
 _rev: string;
  pageData: PageData;
  prismicData?: PrismicData;
ok we are cooking with fire, thanks! this is so much nicer than manually creating this with zod lol
Apr 2, 2024, 4:25 PM
Great to hear 😄
