#8687 is a previous issue I opened. Might be related to it.

I'm building my electron app for multiplatform & cross arch.

Here the electron-builder configuration for Windows

win:

    - target: nsis
      arch: [x64, ia32, arm64]
    - target: msi
      arch: [x64, ia32, arm64]
    - target: portable
      arch: [x64, ia32, arm64]
    - target: zip
      arch: [x64, ia32, arm64]
    - target: 7z

• While building arm64 artifacts.

Here's the repo for failing build, and the workflow run and the electron-builder.yml.

---

But the most confusing thing is when using same configuration for the same electron app in [this repo], but only with Windows configurations, it builds without any errors.

Here the repo and actions workflow run and electron-builder.yml of the same application that's building succesfully.

---

I'm so lost here. Is it because I'm building for all platforms in the first repo I mentioned here? Or what?

FOUND OUT!?

Setting arch does not override defaultArch

Here, I removed defaultArch and the error is gone.

As far as I understand, setting arch does not override defaultArch! , maybe?
