I have a contract with getter `get_max_abs_position_size` that takes trades address and token assetId, after building abi I got two of those types that are equivalent to AssetId and Address in Rust SDK ```auto export type AddressInput = { value: string }; export type AssetIdInput = { value: string }; ``` So I implemented func simulation this way ```auto const result = await clearingHouse.functions .get_max_abs_position_size(addressInput, baseAsset) .addContracts([ contracts?.accountBalanceAbi, contracts?.proxyAbi, contracts?.clearingHouseAbi, contracts?.vaultAbi, contracts?.insuranceFundAbi, ]) .simulate(); ``` But it fails with this error ![image](https://us1.discourse-cdn.com/flex022/uploads/fuel/original/2X/1/1649ec22f956cfe0e259927e81a812b5d9f3b236.png) Logs of my arguments ```auto {value: '0x46553ae0c503dbd4a0a545280a4fe43ca8951a6a364131df8cc7a271c0cf2693'} {value: '0x26829bff466f19001665597228458372fd57cbd325864c7118b5eb5441c42157'} ``` ---

Good find @sway , we are incorrectly encoding this type. I’ve created an issue for it, you can track the progress [here](https://github.com/FuelLabs/fuels-ts/issues/1475). ---

cool, maybe you can provide me fuels version with a fix? It’s really blocking me atm, same way fix for typegen was done in “fuels”: “0.0.0-pr-1468-20231129113808” ---

@sway Would be great if you could confirm if that PR version solves it for you also. ---

> [@danielbate](#): > > fuels@0.0.0-pr-1476-20231204212753 I got a different error, I am not sure if it’s related to wrong call, because there is nothing much to do wrong in simulate ```ts updateMaxValueForMarket = async (clearingHouse: ClearingHouseAbi) => { this.setMaxAbsPositionSize({ long: new BN(71428571), short: new BN(71428571) }); const { tradeStore, accountStore } = this.rootStore; const addressInput = accountStore.addressInput; const baseAsset = { value: TOKENS_BY_SYMBOL.BTC.assetId }; const contracts = tradeStore.contractsToRead; if (addressInput == null || contracts == null) return; const result = await clearingHouse.functions .get_max_abs_position_size(addressInput, baseAsset) .addContracts([ contracts?.accountBalanceAbi, contracts?.proxyAbi, contracts?.clearingHouseAbi, contracts?.vaultAbi, contracts?.insuranceFundAbi, ]) .simulate(); console.log("result", result.value); }; ``` ---

With the above example I am not able to recreate the problem. Are you able to reproduce in a minimalistic repository? ---

Okay so given this error is of type `Revert` we know that it is happening inside the script call (something within the contract), we know that the `AssetId` encoding fix is working. So the above issue has been resolved and let’s deal with the issue with the contract in isolation, outside of this forum post. ---
