How do I debug and fix IntrospectionError | Dagger | Page 1

I have a large configuration object schema that I'm defining with zod, then infering it's type like so.

const ConfigSchema = z.object({
  // ...
});

export type Config = z.infer<typeof ConfigSchema>;

This is used to load, parse, and validate a JSON file passed to a Dagger function.

@func()
private static async loadConfigFile(file: File): Promise<Config> {
  return ConfigSchema.parse(JSON.parse(await file.contents())) as Config;
}

However, when I try to import the module that exposes this loadConfigFile function I get an IntrospectionError.

Error logs:
