I try to use jsonUtils.toObject with a json string or a json object as parameter in the javascript console in Alfresco Enterprise 4.1.5, and getting the following errors.

<blockquote>
<strong>Reference:</strong>
http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Freferences%2Fapi-ws-ob...


toObject(jsonString)
Takes a JSON string and converts it to a native JavaScript object.

toObject(jsonObject)
Takes a JSON object and converts it to a native JavaScript object.

<strong>Test 1</strong>
                
var jsonString = '{"test": "test"}';
logger.log( jsonUtils.toObject(jsonString) );

write like this 

var jsonString = '{"test": "test"}';
 jsonUtils.toObject(jsonString) ;
‍‍‍‍

jsonUtils will convert it correctly, but you can't pass the return result to logger.log(),logger.log only accept string parameter.
so 

logger.log( jsonUtils.toObject(jsonString) );
‍‍‍

will not work ,but 
 var jsonString = '{"test": "test"}';
 jsonUtils.toObject(jsonString) ;‍‍
will work

or you can use double quote mark format string

var jsonString  = "{\"lastName\":\"zhang\",\"location\":\"N.A\",\"firstName\":\"kayne\"}";
    jsonUtils.toObject(jsonString);
‍‍‍‍


you can't use json object directly like below 

var jsonString = {'test': 'test'};
jsonUtils.toObject(jsonString); 
‍‍‍‍
, It 'll throw null pointer exception
