InternalError = 'Wrong fee cache, please try later' when trying to deposit to liquidity pool

Hi everyone,

I am relatively new to building apps on ICP and currently I am working on an app that will allow users to swap ICP with another supported token, same as on ICP Swap.

I am using the @dfinity npm packages to create identity, actors and http agents with nodejs and Javascript, but I get stuck when trying to deposit funds to the pool.

The error message I am getting is: InternalError = ‘Wrong fee cache, please try later’

Here is the code that fails:

    const identity = Secp256k1KeyIdentity.fromSeedPhrase(seed)

    const agent = new HttpAgent({
      identity,
      host: 'https://ic0.app',

    const poolCanisterId = 'mohjv-bqaaa-aaaag-qjyia-cai'
    const poolActor = Actor.createActor(
      poolIdl,
      { agent, canisterId: poolCanisterId },
    )

    const token1Actor = Actor.createActor(
      tokenIdl,
      { agent, canisterId: 'ryjl3-tyaaa-aaaaa-aaaba-cai' },
    )

    const approve = await token1Actor.icrc2_approve({
      fee: [],
      memo: [],
      from_subaccount: [],
      created_at_time: [],
      amount: amount * 10,
      expected_allowance: [],
      expires_at: [],
      spender: {
        owner: Principal.fromText(poolCanisterId),
        subaccount: [],
      },
    })

    const depositResult = await poolActor.depositFrom({
      token: 'ryjl3-tyaaa-aaaaa-aaaba-cai',
      amount: 1000000,
      fee: 30000,
    });

No matter what I try the last line fails with the error. I tried increasing the fee, decreasing it, calculating to be exactly 0.3%, but no luck.

I also tried the deposit method on the poolActor class. Same error.

Can anyone point me to what steps I need to take in order to make a successful swap?

Thanks
