'@ts-expect-error' directive breaking build

Hi, I have just recently made a migration from Angular 17 to 19, and with that, I also updated Angular Shepherd ("angular-shepherd": "^19.0.2",) and all necessary dependencies.
But the problem is that when I run to build the application or even run it locally, I get the following:

X [ERROR] TS2578: Unused '@ts-expect-error' directive. [plugin angular-compiler]

    node_modules/shepherd.js/src/step.ts:582:8:
      582 │         // @ts-expect-error TODO: fix this type error

In my tsconfig.json I already have "exclude": ["node_modules", "tmp"], but it still causes issue in my application.

Can anyone help me out with this?

angular-shepherd 19.0.2 を使用した Angular 19 のビルドから始め、未使用のディレクティブが報告されている shepherd.js/src/step.ts の 582 行目を調査します。失敗を確認し、TS2578 なしでアプリケーションをビルドできるようにするために必要な変更を特定します。
