Cannot create an asset via RPC

Question

$addr = "1ZGADSt8YgXLP2x1gZ8QLATTQGszp2htEBfE81";
$ass = $_GET["asset"];
$a = 'curl -s --user multichainrpc:PASSWORD --data-binary \'';
$b = '{"jsonrpc": "1.0", "id":"curltest", "method": "issue", "params":["';
$c = '", "';
$d = '", 1000, 1';
$e = '] }\' -H "content-type: text/plain;" http://127.0.0.1:6298/';
$cmd = $a  . $b . $addr . c . $ass  . $d . $e;

Calling it from remote in a PHP file,

The raw result is

{"result":null,"error":{"code":-5,"message":"Invalid address"},"id":"curltest"}

Invalid address.
What am I doing wrong?

Answer 1

The best way to debug this kind of thing is to issue the command in multichain-cli, and make a copy of the JSON payload output in the first line. Then get your own code to outputs its JSON payload to some place you can copy from. Then compare the two copies.
