How to encode more complex data types like structs and bytes?

[zkSoju]

I'm trying to use useContractRead with this function quoteLayerZeroFee(uint16 chainId, bytes memory payload, IStargateRouter.lzTxObj memory lzParams) but it's giving me this error for all three inputs, which makes me think that it's trying to convert each argument to a BigNumber:

Error: invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.6.2)

I'm using encode from ethers to get the bytes and an array to create the struct.

useContractRead doesn't force anything internally. If you post a minimal example here, maybe someone can take a look.

Oh I see. Sure!

Smart contract

   function quoteLayerZeroFee(
        uint16 chainId,
        bytes memory payload,
        IStargateRouter.lzTxObj memory lzParams
    )
...
    struct lzTxObj {
        uint256 dstGasForCall;
        uint256 dstNativeAmount;
        bytes dstNativeAddr;
    }

Frontend

const { data: feeData } = useContractRead(
   {
     addressOrName: contractAddress,
     contractInterface: ABI,
   },
   "quoteLayerZeroFee",
   {
     args: [
       10010,
       abiCoder.encode(
         ["address", "uint", "address"],
         [
           "0x79092A805f1cf9B0F5bE3c5A296De6e51c1DEd54",
           0,
           "0x79092A805f1cf9B0F5bE3c5A296De6e51c1DEd54",
         ]
       ),
       [500000, 0, "0x"],
     ],
   }
 );

I also tried some versions of encode for the struct as well but with no luck.
