where can i download the dataprocessor.js???

I posted a few threads and seems nobody here wants to help.
But where is the dataprocessor.js??? it’s not in any of the zip i downloaded.
Something i have to pay for???
Without this file how could we use the connector???
why put connectors available to download when dataprocessor.js is missing?

dataprocessor is included in dhtmlxscheduler.js ( or touchui.js if you are using mobile version )

Without this file how could we use the connector???
Both packages includes all necessary code and working sample for server side integration.
