MongoDB backups turn out to be < 1kb when OPLog is 10 GB

I use separate servers for MySQL, MongoDB and Web workers on Forge and if i backup the MySQL database, it has the right size. The MongoDB backup seems to have less than 1 kb in size, which means nothing is dumped.

I don't think it's because i use the Private Network for this, since i doubted this for a while until i found out that MySQL is under the same network and it dumps correctly.

On staging, everything is running under the same server, and the backups seem to run well and have the correct size.

I tried running MongoDB locally and it seems it does the same thing (this is what outputs when i run php artisan backup:run --only-db --db-name=mongodb; this happens both on production and locally):

Starting backup...
Dumping database production...
Determining files to backup...
Zipping 1 files...
Created zip containing 1 files. Size is 181 B
Copying zip to disk named do-spaces-backups...
Successfully copied zip to disk named do-spaces-backups.
Backup completed!

I tried running these two files separately: #92 (comment)

No success, sadly.

For all future guys that search stuff on Google and reach this issue: update your backup.php file when you upgrade from major to major versions. 🙄
