Is it possible to pass an address array to an eth contract function with transact_and_wait ?

[LouisRandaxhe]

Hello, I am trying to transact with an eth contract method that take an address[] memory in arguments.

When I try to pass this array in args of transact_and_wait in my rails app, I have this error : Could not parse address: ["...", "...", ...].

How can I solve that problem ?

Hi,

I would like to be able to do the same.

I am trying to transact with an eth contract method that take an address[] memory in arguments. When I try to pass this array in args of transact_and_wait in my rails app, I have the following error : Could not parse address: ["...", "...", ...].

Thank you for your work.

Thanks for raising this. Could you show me an example contract or transaction that causes this issue?

Hello,

Here is the Solidity contract function signatures : function distributeNewIncome(uint amount, address[] memory validAddresses) public

And here is how I call it in my Rails app :

@eth = Ethereum.new #instantiate my Ethereum.rb class (see below)

def distribute_income_to_users(contract_address, amount)
    begin
      contract = get_contract(contract_address)
      valid_addresses = Wallet.all.select{|w| w.user.kyc.accepted?}.map{|w| w.eth_address}.to_a #I tried with an array and an array.to_s
      @eth.transact_with_contract(contract,"distributeNewIncome", amount, valid_addresses)
    rescue => e
      raise e
    end
  end

Finally here is the 'transact_with_contract' in my Ethereum.rb file :

@client = Eth::Client.create Parameter.find_by_key("eth_endpoint").value #connection to polygon test network with endpoint saved in db

def transact_with_contract(contract, method, *args) #transaction with contract
    begin
      puts '---Begin transaction---'
      hash = @client.transact_and_wait(contract, method, *args, sender_key: @key, legacy: true, gas_limit: 4000000)
      raise "---Transaction not mined---" unless @client.is_mined_tx?(hash)
      hash
    rescue => e
      raise '---Error---'
    end
  end

Do you have any idea when you can solve the problem please?

Thank you very much!

I really need to work with your gem and I'm still stuck with this issue.

Will you have time to solve the problem soon?

Thanks a lot!
