Improve error in case of invalid specification

[mgm1313]

Edit: I found out the issue is within my specification. If I paste an example YAML, the build does work. Would be nice if the error message was more specific on this!

I'm creating a proof of concept for using Skiffa in our Buchung monorepo. I followed the examples as closely as possible, but the skiffa-generator throws an error.

initialize.js:

#!/usr/bin/env node
import { execFileSync } from "child_process";
import path from "path";
import { fileURLToPath } from "url";

const dirname = path.dirname(fileURLToPath(import.meta.url));
const workspaceRoot = path.resolve(dirname, "..");

const options = { shell: true, stdio: "inherit", env: process.env };

execFileSync(
  "pnpm",
  [
    "--package",
    "@skiffa/generator@0.13.17",
    "dlx",
    "skiffa-generator",
    "package",
    path.resolve(workspaceRoot, "specifications", "api.yaml"),
    "--package-directory",
    path.resolve(workspaceRoot, "generated", "sdk"),
    "--package-name",
    "@buchungapp/sdk",
    "--package-version",
    "0.1.0",
  ],
  options,
);

execFileSync("pnpm", ["--filter", "@buchungapp/sdk", "install"], options);
execFileSync("pnpm", ["--filter", "@buchungapp/sdk", "build"], options);

I'm having trouble because the error message isn't very helpful. I'm not sure what's going wrong.
