unserialize(): Error at offset 0 of 60695 bytes Hey guys I am getting this error:
unserialize(): Error at offset 0 of 60695 bytes
when i push a backup of my local db to my staging environment. 
I am using craft 3.
Any ideas? Clearing the /storage/runtime/cache didn't work.

More info here:
The value that php is trying to unserialize() and failing to do so looks like json (The value of info config, see picture below). 
Looking at an old version of a db dump, that value looks like it was proper serialized data. 
At some point, craft started storing it as json?
Adding a "^" to the craftcms version in the composer.json file and then running composer update, did the trick for me.

for example: "craftcms/cms": "^3.1.22",

I also cleared the cache folder in /storage/runtime/cache
