Output file has not been built from source file, only inside +*.ts files.

Describe the bug

My project imports some types from as typescript references.

// tsconfig.json
{
  "extends": "./.svelte-kit/tsconfig.json",
  "compilerOptions": {
    "allowJs": true,
    "checkJs": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true,
    "skipLibCheck": true,
    "sourceMap": true,
    "strict": true,
    "moduleResolution": "bundler",
    "composite": true
  },
  "references": [
    {
      "path": "../api/tsconfig.json"
    }
  ]
}

// package.json
 "devDependencies": {
    "api": "file:../api",
}

This works fine in all ts files:

// file.ts
import { AppType } from 'api/src/types';

But not for example my layout:

// +layout.server.ts
import { AppType } from 'api/src/types'; // Error: Output file '.../api/src/types.d.ts' has not been built from source file '.../api/src/types.ts'.ts(6305

Reproduction

Difficult for me to setup a codesandbox since these a local references. I also don't know if this is a bug or tsconfig misconfiguration on my part.

@Conduitry Why the label, should I provide more info?

Yes, there's not much we can do with an issue like this without a reproduction.
