The JSON.Parse function in Google Apps Script is leading to a 'server connection error' message during debugging

I'm not a professional developer, but I do code occasionally. Currently, I am working on some Apps Script code to interact with an API and store the data in SQL. Most of it is working fine, but I have encountered an issue while debugging in the Apps Script editor. Whenever I try to access a specific line of code, the editor throws a "could not connect to server" message at the top.


    var response = UrlFetchApp.fetch(clientApiURL,options);
    var resultSet = JSON.parse(response.getContentText());  <-- this is causing the IDE to crash

Does anyone have any suggestions on how to troubleshoot this situation better? The code functions correctly when not in debugging mode, but I need the debugger to analyze objects as the API has varying formats. Unfortunately, the editor crashes when I attempt to do so.

Any help or insight would be greatly appreciated. I have also included the value of response.getContentText() below:


    {"result":{"lead":[{"id":"332","accountID":null,"ownerID":null,"companyName":"", ... snip ... ,"leadStatus":"customer","persona":"","product_5e554b933fb5b":""}]},"error":null,"id":"5222020","callCount":"215","queryLimit":"50000"}

This code snippet reproduces the error:

function test(){
 var obj={"result":{"lead":[{"id":"332","accountID":null,"ownerID":null,"companyName":"", ... snip ... ,"leadStatus":"customer","persona":"","product_5e554b933fb5b":""}]},"error":null,"id":"5222020","callCount":"215","queryLimit":"50000"} 
 var resultSet = JSON.parse(obj);
}

Answer №1

Examining the issue at hand:

function analyze(){
 var data={"result":{"lead":[{"id":"332","accountID":null,"ownerID":null,"companyName":"","title":null,"firstName":"RYAN","lastName":"CAVANAUGH","street":null,"city":null,"country":null,"state":null,"zipcode":null,"emailAddress":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="03666e626a6f43...","createTimestamp":"2020-05-03 20:23:29","leadScoreWeighted":"23","leadScore":"26","isUnsubscribed":"0","leadStatus":"customer","persona":"","product_5e554b933fb5b":""}]},"error":null,"id":"5222020","callCount":"215","queryLimit":"50000"} 
 var result = JSON.parse(JSON.stringify(data));
}

However, the purpose of parsing is to convert a string into an object, not the other way around.

Identifying the issue: 'Unable to establish server connection'

A potential solution has been found:

function analyze(){
 var data='{"result":{"lead":[{"id":"332","accountID":"","ownerID":"","companyName":"","title":"","firstName":"RYAN","lastName":"CAVANAUGH","street":"","city":"","country":"","state":"","zipcode":"","emailAddress":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2d48404c44416d67...","createTimestamp":"2020-05-03 20:23:29","leadScoreWeighted":"23","leadScore":"26","isUnsubscribed":"0","leadStatus":"customer","persona":"","product_5e554b933fb5b":""}]},"error":"","id":"5222020","callCount":"215","queryLimit":"50000"}'; 
 var result = JSON.parse(data);
 var message="is near";//Added a placeholder for debugging purposes
}

All occurrences of null have been replaced with "".
