electron-builder: App rejected when Mac Developer certificate is in keychain

• Version: 7.25.0

• Target: macOS

I wanted to get auto updates working by signing the macOS app so I installed Xcode and created a Mac Development certificate in the Preferences/Accounts panel on my Apple ID (don’t have a real Developer ID yet). Now electron-builder gives me an error in the build process. If I revoke the certificate the error goes away. It actually creates a working .app, but no .dmg or .zip as before.

⚠️  Application icon is not set, default Electron icon will be used
⚠️  Mac Developer is used to sign app — it is only for development and testing, not for production
Signing app (identity: Mac Developer: ****@**.** (LFH******))
