console.log DeclarationError: Undeclared identifier in Solidity

Issue: console.log is throwing an error in remix.

Code :

contract LoanFactory {
    Loan[] loans;

    constructor() {}

    function createLoan() external {
        Loan loan = new Loan(100);
        loans.push(loan);
        console.log(loan);
        address(loan); 
    }
}

Error :

[Aniket-Engg]

As of now, there is no support for complex data types

@SaikrishnaReddy1919 seems loan is a struct variable, that can be reason of error. You can try to log individual property.
