I got this error while I try to run the first test.

contract :

    {
        Listing memory listedItem = s_listings[nftAddress][tokenId];
        if (msg.value < listedItem.price) {
            revert NftMarketplace__PriceNotMet(
                nftAddress,
                tokenId,
                listedItem.price
            );
        }

Hey @khodehSoroush i see an error in this section

await playerConnectedNftMarketplace.buyItem(basicNft.address, TOKEN_ID),
          { value: PRICE };

the { value: PRICE} should be inside the function call. It should be something like this

await playerConnectedNftMarketplace.buyItem(basicNft.address, TOKEN_ID, { value: PRICE });

Try that and tell me if it works

[khodehSoroush]

Yes the problem solved,
THANK YOU for helping me🫂
