TypeError: Type contract InsuranceClaim is not implicitly convertible to expected type address

Question

I am confused why the following code is not working. Any help would be greatly appreciated.

pragma solidity >=0.4.22 <0.6.0

contract InsuranceClaimFactory{
    address public claimer;
    address[] public deployedInsuranceClaim;
    function createInsuranceClaim () public {
        address newInsuranceClaim = new InsuranceClaim(msg.sender);
        deployedInsuranceClaim.push(newInsuranceClaim);
    }

    function getDeployedInsuranceClaims () public view returns (address[] memory){
        return deployedInsuranceClaim;
    }
}

The constructor for InsuranceClaim is

constructor (address creator) public {
claimer=creator;
}

The error is

TypeError: Type contract InsuranceClaim is not implicitly convertible to expected type address

Answer 1

ERROR: Type contract InsuranceClaim is not implicitly convertible to expected type address means you can not store InsuranceClaim type of object in address variable. AS per solidity version 0.5.0 Documentation you can define and use InsuranceClaim like this:

pragma solidity>0.4.99<0.6.0;

contract InsuranceClaimFactory{
    address public claimer;
   
    InsuranceClaim[] public deployedInsuranceClaim;
    function createInsuranceClaim () public {
        InsuranceClaim newInsuranceClaim = new InsuranceClaim(msg.sender);
        deployedInsuranceClaim.push(address(newInsuranceClaim));
    }

    function getDeployedInsuranceClaims () public view returns (InsuranceClaim[] memory){
        return deployedInsuranceClaim;
    }
}

Answer 2

you can do

address newInsuranceClaim = address(new InsuranceClaim(msg.sender));

and it would work fine

Answer 3

  function createInsuranceClaim () public {
        // type is InsuranceClaim
        InsuranceClaim newInsuranceClaim = new InsuranceClaim(msg.sender);
        //                     push the address of new contract
        deployedInsuranceClaim.push(address(newInsuranceClaim));
    }

Answer 4

If you are working with version >=0.8, you need:

InsuranceClaim newInsuranceClaim = new InsuranceClaim(msg.sender);
deployedInsuranceClaim.push(payable(address(newInsuranceClaim)));

Note the use of payable here.
