Cannot parse blockmap when auto updating

• Electron Builder Version: 22.4.0

• Electron Updater Version: 4.2.4

• Target: NSIS

My app is updating from a private github repo and when the update check starts it never downloads differentially because of the following error. Cannot download differentially, fallback to full download: Error: Cannot parse blockmap "https://api.github.com/repos/VitruxPT/w-assistant/releases/assets/18470277.blockmap", error: incorrect header check, raw data:...

The publish command always works fine and all the files (exe, blockmap, latest.yml) are being sent to the repo sucessfully so I’m not sure if this is on my end.

This is how my main.log looks like:

Thanks in advance

I made a PR to fix this issue.

To fix it immediately on your release computer do the following

• Open node_modules/electron-updater/out/NsisUpdater.js
• Goto line number 272 and replace the line with the following

 return JSON.parse((0, _zlib().gunzipSync)(data).toString());
