Code:

  const { native } = useMoralisWeb3Api();
  const { farmAddress, farmAbi } = useFarm();

  const options = {
    chain: "bsc testnet",
    address: farmAddress,
    function_name: "getTokens",
    abi: farmAbi,
  };

  const { fetch, data, error, isLoading } = useMoralisWeb3ApiCall(
    native.runContractFunction,
    options
  );

Error:

Looks like you’re using TypeScript, if so, you can try adding types to your options

  const options: {
    chain: "bsc testnet";
    address: string;
    abi: object[];
    function_name: string;
  } = {
    chain: "bsc testnet",
    address: farmAddress,
    function_name: "getTokens",
    abi: farmAbi,
  };

const chain = “bsc testnet”
const option = {
chain: chain as any,
address: farmAddress,
function_name: “getTokens”,
abi: farmAbi,
};
Please try this

chain as any too should work, but regards typescript, it’s better to have the expected type at most.
