get data from another contract (solidity)

I'm new in developing contracts and i'm developing a React Dapp. in this context I have to get a list of details from another contract. here are the details : I have contract JobOffer which have a list of candidacy ( mapping(uint256 => address[]) idJobAddressCandidat; ) unit256 present the id of candidacy and those addresses are the addresses of candidate. the whole information of candidate is stocked by another contract called contract CVStorage this contract have a function which returns all the informations :

function getAllDetails(address _addressCandidat)
        public
        view
        returns (CV memory)
    {
        return CVs[_addressCandidat];

the problem is: I want to get the list of details for each address linked to an id of candidacy in the mapping ( returning a list of details of candidates in a candidacy) ; the signature of the function i want to develop is : getAllCandidaturesOfJobOffer(uint256 _idJobOffer) public view returns ( CV [] memory )

PS : I tried to get all those information from the front end (React) by getting the array of addresses of a candidacy using this function :

function getAllCandidaturesOfJobOffer(uint256 _idJobOffer)
        public
        view
        returns (address[] memory)
    {
        return idJobAddressCandidat[_idJobOffer];
    }

and then i get for each address the data from the other CVStorage contract ( using the function getAllDetails(address _addressCandidat) but unfortunately i got usually an error maybe because I shouldn't call two contracts in the same function or two await methods in the same function. thanks for giving me your time.
