eth_signTypedData_v4 when trying to fulfill an order

[BravoNatalie]

I'm trying to execute the following code but I'm having this error:

const { executeAllActions } = await seaport.createOrder(
      {
        offer: [
          {
            amount: ethers.utils
              .parseEther(asset.sellOrder.currentPrice)
              .toString(),
          },
        ],
        consideration: [
          {
            itemType: ItemType.ERC721,
            token: "0x13b9ba7c61c7774089fbfce6cffc22021fb14110",
            recipient: asset.owner,
            identifier: asset.tokenId,
          },
        ],
      },
      asset.owner
    );

    const order = await executeAllActions();
    console.log("====> ", order);

    const { executeAllActions: executeAllFulfillActions } =
      await seaport.fulfillOrder({
        order,
        accountAddress: connectedWallet,
      });

    const transaction = await executeAllFulfillActions();

I've solved the error. This was happening because I was using a jsonProvider, which does not contain any signer information. The solution was to instantiate the Seaport with the signer.
