TypeError: types.filter is not a function

[lasnab]

Hi all, Getting a type error when running npx sanity-codegen. Followed the tutorial as described in the readme, double checked all the paths, dependencies and tried running in both with sanity-codegen.config.ts in the sanity app directory, and also having it in my project root directory, getting the same error. My project is organized as follows -

project -
    - sanity-studio
    - src
    - other files for react

Note: React was initialized with typescript (so was sanity studio).

I'm having the same problem 😭

Does anyone have a solution yet?

This seemed to work for me https://github.com/ricokahler/sanity-codegen/issues/272#issuecomment-1241092032

TL;DR

The codegen plugin expects that the index file has a default export. The Sanity 3.0.0 generator gives a named export Simply adding export default schemaTypes to the end of schemas/index.ts fixes this

Eg for me, I have this in schemas/index.ts:

import blockContent from './blockContent';
import category from './category';
import post from './post';
import author from './author';

export const schemaTypes = [
  post,
  author,
  category,
  blockContent,
];

export default schemaTypes;

Can't believe sanity didn't update this with their main package, I hope they fix this soon so it can work out of box.

Worked for me, king! 👑
