Invalid replacer argument

An attempt has been made to invoke JSON.stringify with an argument that is not valid. The replacer argument must be a function or an array.

To correct this error

  • Change the replacer argument to a function or an array.

Example

The code in this example causes a runtime error because memberfilter is an object instead of a function or array.

var contact = new Object();  
contact.firstname = "Jesper";  
contact.surname = "Aaberg";  
contact.phone = ["555-0100", "555-0120"];  

var memberfilter = new Object();  

// This line will cause a runtime error.  
var jsontext = JSON.stringify(contact, memberfilter, "\t");
