Is it not possible to stringify an Error using JSON stringify

Question

Reproducing the problem  I m running into an issue when trying to pass error messages around using web sockets  I can replicate the issue I am facing using JSON stringify to cater to a wider audience      node v0 10 15  gt  var error   new Error  simple error message        undefined   gt  error      Error  simple error message    gt  Object getOwnPropertyNames error          stack    arguments    type    message      gt  JSON stringify error              The problem is that I end up with an empty object   What I ve tried  Browsers  I first tried leaving node js and running it in various browsers  Chrome version 28 gives me the same result  and interestingly enough  Firefox at least makes an attempt but left out the message    gt  gt  gt  JSON stringify error      Firebug  Firefox 23   fileName   debug eval code   lineNumber  1  stack    debug eval code 1 n     Replacer function  I then looked at the Error prototype  It shows that the prototype contains methods such as toString and toSource  Knowing that functions can t be stringified  I included a replacer function when calling JSON stringify to remove all functions  but then realized that it too had some weird behavior   var error   new Error  simple error message    JSON stringify error  function key  value        console log key             true         console log value     error      true           It doesn t seem to loop over the object as it normally would  and therefore I can t check if the key is a function and ignore it   The Question  Is there any way to stringify native Error messages with JSON stringify  If not  why does this behavior occur   Methods of getting around this   Stick with simple string-based error messages  or create personal error objects and don t rely on the native Error object  Pull properties  JSON stringify   message  error message  stack  error stack      Updates   Ray Toal Suggested in a comment that I take a look at the property descriptors  It is clear now why it does not work   var error   new Error  simple error message    var propertyNames   Object getOwnPropertyNames error   var descriptor  for  var property  i   0  len   propertyNames length  i  lt  len    i        property   propertyNames i       descriptor   Object getOwnPropertyDescriptor error  property       console log property  descriptor       Output   stack   get   Function     set   Function     enumerable  false    configurable  true   arguments   value  undefined    writable  true    enumerable  false    configurable  true   type   value  undefined    writable  true    enumerable  false    configurable  true   message   value   simple error message     writable  true    enumerable  false    configurable  true     Key  enumerable  false   Accepted answer provides a workaround for this problem
