Appflow Build: „Module not found" from Private Gitub Repo

I’m currently setting up my first AppFlow Build.

I have a private Github Repo, which i install in my Application. This seems to work as the npm install Step works well.

In the Build step i get errors for every usage of my Package like:

Error: src/app/all/chat/chat.page.ts:15:39 - error TS2307: Cannot find module 'my-module' or its corresponding type declarations.
[11:58:31]: ▸ 15 import { ErrorCodes, PushCodes } from 'my-module';

When i run the same Command locally it builds perfectly.

I already opened a Ticket at Ionic Support, but maybe one of you is faster :sweat_smile:
