Relevant part:

// 
for await (const line of rl) {
        if (!line) continue;
debug(`Current line: ${line}`);
        const cacheEntry = JSON.parse(line);
// ...
}

I added the debug. And yes, line is just invalid json.

Log:

Hello @tobiasb
Can you provide this file to me in a private message?

[girish]

I was able to easily reproduce this. Something to do with the filename

[girish]

Fixed - https://git.cloudron.io/platform/box/-/commit/6e0dc24ecae47ba3175ce1574a86c6724fbc98aa . Thanks for debugging @tobiasb and thanks for reporting @luckow

I'm facing a similar issue, with a new file downloaded today and renamed afterwards, the backup is for syncthing.

The fix is not released.

You could back up the app with another backup destination which does not uses rsync or patch the file manually with https://git.cloudron.io/platform/box/-/commit/6e0dc24ecae47ba3175ce1574a86c6724fbc98aa.diff
