Calculate fees with Blocktrail/btc.com SDK

Calculate fees with Blocktrail/btc.com SDK

First of all hi and thanks for your support and your time.

I want to calculate the fees of a blocktrail transaction with blocktrail SDK, before making the transaction, in order to let the recipient pay fees.

Here is what I tried:

$FEES = $wallet->coinSelection(\Blocktrail\SDK\Wallet::normalizeOutputsStruct(['66f4dec6ab29cd056ce1814c6fdfee05e1524b36' =>'100000']),false,false,\Blocktrail\SDK\Wallet::FEE_STRATEGY_LOW_PRIORITY['fee'];
echo "$FEES";

But this don't work, it says this: Fatal error: Uncaught Blocktrail\SDK\Exceptions\BlocktrailSDKException: Address not recognized how can I fix this error? Thanks for read, hope that you'll have a nice day :)
