Related to ballerina-platform/ballerina-lang#30106

2. Parameter type name is NULL when parameter type kind is NON_NULL.

This is the expected behavior.

The returning of the incorrect values for default values is actually a design limitation. We do not have a way to get the default value of an input parameter at the runtime. This is known at the time of implementation and as a temporary workaround, we used zeroValue of the input type as the default value, if an input parameter has a default value.

This does not affect the execution, since at the execution phase, since the default value is used from the runtime when we execute the function. The issue is the default value shown in the introspection queries is wrong.

Until the related lang issue (ballerina-platform/ballerina-lang#30106) is fixed, this cannot be done. Therefore, removing the Bug label, and adding Task label.

Closing as the remaining issue is tracked using #4720
