FuelError: Invalid u64

TypeScript SDK
1

I am trying to make a contract call in TS.
Fuels TS:- 0.94.0

fuel-toolchain.toml
forc = “0.63.1”
fuel-core = “0.33.0”

My TS call:-

    const provider = await getProvider();
    const contract = await getContract();
    const latestBlock = await provider.getBlock("latest");
    if (latestBlock) {
      const duration = 60 * 60 * 1000;
      console.log(latestBlock.time);
      const start = +latestBlock.time;
      const end = start + duration;
      console.log(start);
      console.log(end);

      const poolId =
        "0x0000000000000000000000000000000000000000000000000000000000000009";

      const call = await contract.functions
        .create_pool(poolId, start, end)
        .txParams({ gasLimit: 200000 })
        .call();
      const res = await call.waitForResult();
      console.log("res: ", res);
    }
  };```

My sway function

```#[storage(read, write)]
    fn create_pool(pool_id: b256, start_time: u64, end_time: u64) {
        only_owner();
        require(
            storage.pool_data.get(pool_id).try_read().is_none(),
            PoolError::PoolExist,
        );
        let data = PoolData {
            start_time: start_time,
            end_time: end_time,
            pool_amount: 0,
            status: PoolStatus::Active
        };

        storage.pool_data.insert(pool_id, data);
    }```

Hey @chappie1998, could you try implementing the BigNumbers library from fuels and test the same again:

import { bn } from 'fuels';

const provider = await getProvider();
const contract = await getContract();
const latestBlock = await provider.getBlock("latest");

if (latestBlock) {
  const duration = 60 * 60 * 1000;
  console.log(latestBlock.time);
  const start = bn(latestBlock.time);
  const end = start.add(bn(duration));
  console.log(start.toString());
  console.log(end.toString());

  const poolId = "0x0000000000000000000000000000000000000000000000000000000000000009";

  const call = await contract.functions
    .create_pool(poolId, start, end)
    .txParams({ gasLimit: 200000 })
    .call();
  const res = await call.waitForResult();
  console.log("res: ", res);
}
