How to get JSON object values with the JSON keys having spaces in Node.js

This is my JSON object :

var EVENT_ID = {
  "Enable Popup Blocker": "Sol_EnablePopupBlocker_IE",
  "Disable Script Debug": "Sol_DisableScriptDebugger_IE",
  "Clear History": "Sol_ClearHistory_IE",
  "Reset Settings": "Reset_InternetExplorer_Settings_SA",
  "Profile Issue": "Fix_Outlook_Profile_SA",
  "Send Receive": "Fix_Send_Receive_Errors_Outlook_SA",
  "Search Issue": "Fix_Search_Outlook_SA"
};

I am trying to access the JSON object value with keys, which has spaces as shown below

var eventID = JSON.stringify(req.body.result.parameters.solution); 
var aptEventName = EVENT_ID[eventID];

eventID value is "Profile Issue"

When I log my aptEventName variable, it throws values as undefined. Can anyone please tell me, where I am going wrong?

ONE POSSIBLE CASE: when you again do JSON.stringify() on a string value this could happen. That's why it throws values as undefined, so don't use unnecessary JSON.stringify() here 

var response = "response"
JSON.stringify(response)
""response"" 
^^        ^^ see extra quotes here   


var result = { "source": "agent", "resolvedQuery": "LPTP-KDUSHYANT", "speech": "", "action": "gethostname", "actionIncomplete": false, "parameters": { "solution": "Profile Issue", "hostname": "LPTP-KDUSHYANT" }}
var eventID = result.parameters.solution;
var EVENT_ID = {
  "Enable Popup Blocker": "Sol_EnablePopupBlocker_IE",
  "Disable Script Debug": "Sol_DisableScriptDebugger_IE",
  "Clear History": "Sol_ClearHistory_IE",
  "Reset Settings": "Reset_InternetExplorer_Settings_SA",
  "Profile Issue": "Fix_Outlook_Profile_SA",
  "Send Receive": "Fix_Send_Receive_Errors_Outlook_SA",
  "Search Issue": "Fix_Search_Outlook_SA"
};

var aptEventName = EVENT_ID[eventID];
console.log(aptEventName)

You should not be using stringify, it is taking a string and turning that string into JSON.

var eventID =  JSON.stringify(req.body.result.parameters.solution);

when you do this your string is going to be

var eventID = "\"Profile Issue\"";

So of course you have no properties in your object with quotes. So what you need to do is drop the stringify bit and just have to reference the property in your object.

var eventID = req.body.result.parameters.solution;
var aptEventName = EVENT_ID[eventID];

You can get the values using:

EVENT_ID["Clear History"]

I think you have something wroong with the req.body.result.parameters.solution.

JSON.stringify called on a string will return the string in quotes. You should not JSON-encode your key. And as string typecast is implicit when performing object field access you can type it just as:

var eventID = req.body.result.parameters.solution;
var aptEventName = EVENT_ID[eventID];
