Getting fee for message

[bokoskokos]

I am trying to use the GetFeeForMessageAsync method but I seem to get the same result (5000) no matter the transaction message. I must be doing something wrong, does anyone see the issue here?

var blockHash = await rpcClient.GetLatestBlockHashAsync();
var txRaw = new TransactionBuilder().
   SetRecentBlockHash(blockHash.Result.Value.Blockhash).
   SetFeePayer(<PAYER>).
   AddInstruction(TransactionInstructionFactory.Create(
       programId: <PROGRAM_ID>,
       keys: new List<AccountMeta>{ <ACOUNTS> }
   ));
   var txBytes = txRaw.Build(new List<Account> { PAYER });
   var message = Convert.ToBase64String(txRaw.CompileMessage());
   var feeResponse = await rpcClient.GetFeeForMessageAsync(message); // always 5000
   var response = await rpcClient.SendTransactionAsync(txBytes);
