Electron Updater Not Working Due to Missing app-update.yml in NSIS Build - Need Solution

[ranjithrr]

I am using the following setup for building my Electron application:

Electron Builder Version: 20
Electron Version: CastLabs Electron 28
Issue: While creating the "EXE" file with electron-builder using NSIS, the app-update.yml file was not generated automatically. In our previous builds, we manually created the app-update.yml file and placed it in the appropriate directory. However, this time, we forgot to copy the file, and the application was released without it. As a result, the electron-updater is no longer working, which is a critical issue for us.

Questions:

Why was the app-update.yml file not generated automatically during the build process? What might have caused this issue, and how can we ensure it is created every time?

Is there any way to overcome this issue without having to release a completely new build? Can I manually add the app-update.yml file to the installed application, or is there another approach that can resolve this problem?
Any guidance on how to resolve these issues and ensure app-update.yml is always generated during the build process would be greatly appreciated.
