Uncaught Error: Invalid number of arguments to Solidity function

Question

function TriggerContract() { var account = getAccounts(); var test = web3.eth.defaultAccount;

    console.log(account);
    var q = document.getElementById("Quantity").value;
    var u = toHex(document.getElementById("Unit").value);
    var m = toHex(document.getElementById("Material").value);
    var x = contractAddress.countMaterials(function(err, result) {
          if (err) {
            console.log(err)
          } else {
            console.log("Hey")
          }
        });
    console.log(x);
    contractAddress.setMaterial((test,q, u, m) => {
          if (err) {
            console.log(err)
          } else {
            console.log("YES")
          }
        });
    Reset();
  }

I get a "Uncaught Error: Invalid number of arguments to Solidity function" on the following line and have no idea why. The number of arguments should be correct. Any suggestions would be greatly appreciated.

contractAddress.setMaterial((test,q, u, m)

function setMaterial(address _address, uint64 _weight, bytes16 _material, bytes16 _unit) public{
        materials[_address] = Material(_address, _weight, _unit, _material);

        materialAccounts.push(_address) -1;
        emit materialAdded(_materialID);
    }

Answer 1

I believe it is due to the absence of proper callback function. Please try below format and also try without result part( only err).

 functionname  (variables,function (error, result) {

              if (error) {
                  console.log(error)
              }
              else {
            console.log("yes")

              }

Change this:

    contractAddress.setMaterial((test,q, u, m) => {

To this:

    contractAddress.setMaterial(test,q, u, m).then(function(result, err) => {

Since I usually resolve promises with an await rather than a callback function, I'm not 100% sure about the prototype of function(result, err). You should possibly use function(err) instead.
