Solidity: Get mapping from Struct

Question

I'm kinda new to Solidity, sorry for this in advance. I'm building a Dapp and cannot understand how to get a mapping or an array from a Struct. This is the struct that have inside a two mappings and one array.

struct Something {
    uint256 var;
    string[] array;
}

This is the result printed in the console:

{
    var: "17"
}

As you can see, the call returns only level one attributes.

How to get that array from the struct?

Thanks in advance.

It is not possible in solidity for a function to return a variable of type mapping.

The default getter of a public struct variable will not return dynamic data types like mapping or dynamic array.

To access data from dynamic field inside an struct you have to implement your own getter.

function getTaskFreelancer(uint256 taskId, uint256 idx) public view returns (addres) {
    require(_tasks[taskId]._freelancerArray.length > 0, "Invalid freelancer index");
    return _tasks[taskId]._freelancerArray[idx];
}
