Same thing here. The first experience with graffle@next :(

[shishkin]

I just checked and graffle@8.0.0-next.173 (latest next at the time of writing) works fine in a new project following the getting started guide. The issue is observed in an existing project with many dependencies. I also observe the same issue going back as far as 8.0.0-next.157 (9 months old). I was suspicious about Zod, which graffle requires at ^3.24.3 but I have at 4, but installing zod@4 in a new project doesn't trigger the issue. I'm also using pnpm, so it should be able to isolate dependencies (at least I see both zod@3.25.51 and zod@4.1.11 in my lock file). I also update all graphql-related dependencies to their latest versions and still observed the issue.

This seems like a Zod 4 compat issue but I'm not sure. I'd like to upgrade Molt anyways to use Effect schema so maybe that will resolve this issue when I do.

I came across this error; in this case, another dev dependency (knip) was using zod 4+. Removing knip and pnpm update, and the codegen worked again. I think this validates that it's a zod 4 compat issue.

[jasonkuhrt]

This should be fixed by #1477 which migrates the CLI from @molt/command (Zod-based) to Oak with Effect Schema.
