$cfg{xxx} doesn't work on source/destination connectors

[ppazos]

I have a variable 'folder_folder' in the Configuration Map.

In a File Reader connector I can access it via ${source_folder}, but the more specific $cfg{source_folder} doesn't work. When I click Test Read, that value is just empty.

With $cfg{}

With ${}

Then in the Channel Script Deploy I added logger.info($cfg('dest_folder')); which actually displays the correct path in the log when I deploy the channel.

So there is an issue with the $cfg{xxx} access from the Source/Destination Connector configuration, which doesn't happen when accessing from JS with $cfg('xxx').

Any ideas?

I'm on MC 4.4.0

I have seen how $ is implemented. If this implementation is correct, then the behavior I'm seeing doesn't make sense (I have tested all the steps done by $() using $r{xxx}, $co{xxx}, and so on, and all return an empty value).

My guess is there might be a problem translating the expression $cfg{xxx} to $cfg('xxx') for making the JS function call.

function $co(key, value) { if (arguments.length == 1) { return connectorMap.get(key); } else { return connectorMap.put(key, value); } }
function $c(key, value) { if (arguments.length == 1) { return channelMap.get(key); } else { return channelMap.put(key, value); } }
function $s(key, value) { if (arguments.length == 1) { return sourceMap.get(key); } else { return sourceMap.put(key, value); } }
function $gc(key, value) { if (arguments.length == 1) { return globalChannelMap.get(key); } else { return globalChannelMap.put(key, value); } }
function $g(key, value) { if (arguments.length == 1) { return globalMap.get(key); } else { return globalMap.put(key, value); } }
function $cfg(key, value) { if (arguments.length == 1) { return configurationMap.get(key); } else { return configurationMap.put(key, value); } }
function $r(key, value) { if (arguments.length == 1) { return responseMap.get(key); } else { return responseMap.put(key, value); } }
function $(string) { 
    try { if(responseMap.containsKey(string)) { return $r(string); } } catch(e){}
    try { if(connectorMap.containsKey(string)) { return $co(string); } } catch(e){}
    try { if(channelMap.containsKey(string)) { return $c(string); } } catch(e){}
    try { if(sourceMap.containsKey(string)) { return $s(string); } } catch(e){}
    try { if(globalChannelMap.containsKey(string)) { return $gc(string); } } catch(e){}
    try { if(globalMap.containsKey(string)) { return $g(string); } } catch(e){}
    try { if(configurationMap.containsKey(string)) { return $cfg(string); } } catch(e){}
    try { if(resultMap.containsKey(string)) { return resultMap.get(string); } } catch(e){}
    return ''; 
}
