How to use Build Cache with Zip Archive

I'm trying to setup a Build Cache for my E2E Tests on Teamcity Cloud. My cache is only 50mb but has 3.5k files so I am required by Teamcity Cloud to archive it (limit of 1000 files for build cache, can't change this setting in TC Cloud). My cache is for for Jest testing framework. Teamcity is creating a build cache but failing to find it on subsequent runs.

Teamcity is complaining that:
Could not download build cache with name 'jestCache.zip'. Error: No files matched for patterns "" from <bt67, build with id: 60718>

BUILD CACHE SETTINGS:
You can see in the Build Cache settings below, I want to publish from the agent's buildTemp dir  and restore it to there. Exact path is /opt/buildagent/temp/buildTemp/jest_0. I am creating an archive jestCache.zip, so probably would need to unzip it (when TC is able to find it)
