electron-builder: Small Critical Error: Cannot download differentially, fallback to full download: Error: Maximum allowed size is 5 MB

Version: 20.38.5

Target: Windows

Error: Cannot download differentially, fallback to full download: Error: Maximum allowed size is 5 MB.

This Error is only thrown for a private Github repository. If I set it to public again this error is not thrown. Probably a small bug somewhere… I cannot figure out whats wrong 😞

I just got it to work by reverting electron-builder to version 20.38.0 and electron-updater to version 4.0.4. I’m not sure which was causing the problem.

JonKelley88 on Mar 27, 2019

I have reverted everything in my environment back as suggested above and I’m still getting this problem. I am using a private GitHub repo with GH_TOKEN set. Windows is the target. Both my current installation and my new update are built with the same configuration as below:

UPDATE: Despite the error ridden traceback below, it does appear to do the download. However, there seems to be some failure running the update – the end result are zombie icons and the app itself appears to be uninstalled. I presume the update is done silently when you close the app??? I’ve never seen the auto-update work before.

electron: 5.0.0 electron-builder: 20.38.0 electron-updater: 4.0.4

  "installerIcon": "images/LegisPro.ico",
  "installerHeaderIcon": "images/LegisPro.ico",

    "releaseType": "draft"
  }
}

My code is:

autoUpdater.setFeedURL({ provider: “github”, owner: “Xcential-Corporation”, repo: “LegisPro-Sunrise”, token: process.env.GH_TOKEN }); autoUpdater.allowPrerelease = false; // Letting default errors on old releases without latest.yml files autoUpdater.checkForUpdatesAndNotify();

TL;DR; Solved by adding the MIME type to IIS server.

- Electron v 27.0.0 [Stable on 2023-08-10], [EOL on 2024-04-16], https://www.electronjs.org/docs/latest/tutorial/electron-timelines
- Electron-Builder v 24.9.1
- Electron-Updater v 6.1.7 [latest as of 2023-Dec]

In my local development environment I set-up an IIS site to serve the published files, the app detects changes and attempts to download it, eventually it does it but fallbacks to a full download

I added a MIME Type to the server and now it downloads it correctly in blocks

I believe it is fixed by increasing the maximum size allowed to 50MB. But my file is 150MB so this is still an issue for me. Why is there size limit? I’m sorry but I don’t quite understand.

Now using 20.34.0 and the file is downloaded and installed properly despite errors.
