TypeError: Invalid type for argument in function call. Invalid implicit conversion from uint256[3] memory to uint256[] memory requested

so I got a problem while developing a contract using a foundry. So I have a function that takes uint256 with array type as an argument. But when I did the test, It showed an implicit error.

TypeError: Invalid type for argument in function call. Invalid implicit conversion from uint256[3] memory to uint256[] memory requested.

contract Test {
    uint256[] private threshold = [1000, 2000, 3000];

    function setThreshold(uint256[] memory _threshold) public onlyOwner {       
        threshold = _threshold;
    }
}

Does anybody know how to fix this problem?

There is probably an error in your script where you call setThreshold function or error is in your tests.

I've made little changes to your code for simpler check

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract Test {
    uint256[] public threshold = [21000, 2000, 3000];

    function setThreshold(uint256[] memory _threshold) public {
        threshold = _threshold;
    }
}

Here is my deploy script: from brownie import Test, accounts

def main():
    check = Test.deploy({"from": accounts[0]})
    print(check.threshold(0))
    check.setThreshold([1000, 1000, 1000], {"from": accounts[0]})
    print(check.threshold(0))

And here is an output:
