DFINITY R&D Team Announces BTC-ICP Integration Beta Release

Please consider this contract:

pragma solidity 0.8.7;  contract Test {      struct UserStruct {         uint256 betAmount;         uint256[] potentialWinnings;         string teamChosen;}      mapping(address => UserStruct[]) public userStructs;      function appendUserBet(string memory userTeamChosen,uint256 eventNumber) public payable {         UserStruct memory userStruct = UserStruct(msg.value,new uint256[](0),userTeamChosen);         userStructs[msg.sender].push(userStruct);}      function updatePotentialWinnings(uint256 eventNumber,address userId,uint256[] memory potentialWinnings) public {         userStructs[userId][eventNumber].potentialWinnings = potentialWinnings;}} 

It works fine, however when I’m including a function below to the contract, it doesn’t compile. It errors out with TypeError: Invalid type for argument in function call. Invalid implicit conversion from uint256 to uint256[] memory requested.

    function addAllPotentialWinnings(uint256 _eventNumber, uint256[] memory _potentialWinnings, address[] memory _usersList) public {         for (uint i =0; i<_usersList.length;i++){             updatePotentialWinnings(_eventNumber,_usersList[i],_potentialWinnings[i]);}} 

I want to provide an array of arrays (2D-array of dynamic size) as an argument to the function, but I seem to be doing it incorrectly. From what I was able to understand is that UserStruct expects potentialWinnings to be in uint256[] format, but it recieves them as uint256. By design I want to provide the function with an array that looks like this: [[0,1,2],[2,5,6],[x,y,z],...]

How do I change my contract such that it "knows" that the array i’m passing as an argument, is going to have the required arrays inside?

Thank you in advance!
