ERROR
$contract2->at($contractAddress)->call('getID', "123456789012", function ($err, $result) use ($contract2)
If integer value is passed and method returns string, it treated as smart contract error.

WORKING
$contract2->at($contractAddress)->call('getID', "a123456789012", function ($err, $result) use ($contract2)
If string is passed and returns string, it is working properly.

Only number as input is not supported.
