Core builds are failing due because of passing null values to primitive type

[srinugajjala]

Describe the bug
Currently, the null values are being passed to some parameters which are of the primitive type Int which it doesn't accept.

Expected behavior
The build should go through and if the users don't use the optional parameter then it should work with the code flow and the build should pass.

To Reproduce
Just by following the installation procedure, the builds are failing.
