So, the core of the problem is described in title, but
When I commiting changes to schema.prisma my autogenerated export types in ./generated/nexus.ts don't refresh. I also don't see changes in apollo playground on my localhost:4000
I tried to migrate my schema and 'npx generate path to my schema' but they didn't work neither.
Without this I can't proceed with writing mutations and queries because TS can't see new types.
Ok, so I managed to fix it, if any other faced with this problem so the solution can be found here https://github.com/prisma/prisma-examples/blob/latest/typescript/graphql-auth/README.md The main issue was that you have to run your server after migration with db and after changes to schema.ts.
