Pay with forceFee doesn't work

[jmn8718]

Im trying to perfom a pay action forcing the fee to the value i want, i follow the examples of the repo but i can not make it work, this is my code

const payment = {};
payment[destinationAddress] = btcToSatoshi(amount);
const options = {
	forceFee: btcToSatoshi(fee),
	checkFee: false,
}
_wallet.pay(payment, null, false, true, blocktrail.Wallet.FEE_STRATEGY_FORCE_FEE, null, options)

but i get the following error

{ Error: An internal error was encountered

@jmn8718 it's forcefee not forceFee but I'm still getting the same error (though I did it correctly)

This is my own code

const executeTransfer = (identifier, passphrase, address, amount, userId, fee) => {
  return sails.blocktrailClient.initWallet(identifier, passphrase)
    .then((wallet) => {
      const options = {
        forcefee: fee
      }
      let payment = {}
      payment[address] = amount
      return wallet.pay(payment, null, false, true, blocktrail.Wallet.FEE_STRATEGY_FORCE_FEE, null, options)
        .then((txhash) => {
          return buildTransaction(amount, address, userId, txhash) // ignore this
            .then((transaction) => {
              return transaction
            })
        })
        .catch((error) => {
          return error
        })
    })
}
