COUNTLY_CONFIG_API_MONGODB ignored during installation

[Bramzor]

During installation, following errors occur:

Installing plugin "video-intelligence-monetization"...
Installing plugin "alerts"...
Installing alerts plugin
Adding alerts patch
Installing plugin "onboarding"...
Processing plugin files for production mode
Preparing production files
{ MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017]

When specifying a custom mongodb url like:
export COUNTLY_CONFIG_API_MONGODB=mongodb://user:pas@mdbcluster.internal:27017/countly

Expected Behavior

The correct mongodb url should be used when generating countly/api/config.js

Current Behavior

Errors are thrown and value seems to be ignored?

Your Environment
