Hi guys. I would like some help from the senior devs around to help me understand the following runtime error that happened on a Android device (running a Corona Enterprise app).
Runtime Error - errorEvent=[errorMessage]=bad argument #2 to 'tonumber' (number expected, got no value) Runtime Error - errorEvent=[name]=unhandledError Runtime Error - errorEvent=[stackTrace]= stack traceback: [C]: in function 'tonumber' ?: in function \<?:32\> [C]: in function 'gsub' ?: in function 'hexToString' ?: in function '?' ?: in function 'authenticate' ?: in function 'new' ?: in function '?' ?: in function 'listener' /Users/jenkins/slaveroot/workspace/Enterprise/OS/xcode-8.3/release/release/subrepos/timer/timer.lua:210: in function 'method' /Users/jenkins/slaveroot/workspace/Enterprise/OS/xcode-8.3/release/release/platform/resources/init.lua:221: in function \</Users/jenkins/slaveroot/workspace/Enterprise/OS/xcode-8.3/release/release/platform/resources/init.lua:190\>
The function that throw that error was:
function hexToString(hexString) local byteString = (hexString:gsub('..', function (cc) return string.char(tonumber(cc, 16)) end)) return byteString end
As I marked in bold above, the #2 parameter of ’ tonumber’ is 16 , so how could I get a runtime error saying that #2 parameter had ‘no value’?
Also, I never saw the “no value” before… I am used to see “xxxxx expected, got nil”. Is “no value” == “nil”?
Thank you.
