Google Apps Script JSON.Parse causing 'could not connect to server' on debug

Question

I'm by no means what I would call a "developer" but dabble quite a bit. I'm working on some Apps Script code to query an API and push the results into SQL. I have most of the bits working but I've noticed that while I'm debugging in the Apps Script editor, when I step into the following line of code, the editor throws the "could not connect to server message at the top.

    var response = UrlFetchApp.fetch(clientApiURL,options);
    var resultSet = JSON.parse(response.getContentText());  <-- this is the line that is crashing the IDE

Anyone know how to better debug this? When I'm not debugging it, the code seems to behave and function properly. But with this API, not all objects are formatted the same way, so I like to use the debugger to inspect them. I can do that when the editor crashes.

Any help/insight would be super appreciated. I've also pasted below the value of response.getContentText()

    {"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":"email@here.com","website":null,"phoneNumber":null,"officePhoneNumber":null,"phoneNumberExtension":null,"mobilePhoneNumber":null,"faxNumber":null,"description":null,"campaignID":"789934082","trackingID":"202003_5e6fa18a87853a69eb306910","industry":null,"active":"1","isQualified":"1","isContact":"1","isCustomer":"1","status":"4","updateTimestamp":"2020-05-08 20:24:48","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"}

This will reproduce the error:

function test(){
 var obj={"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":"email@here.com","website":null,"phoneNumber":null,"officePhoneNumber":null,"phoneNumberExtension":null,"mobilePhoneNumber":null,"faxNumber":null,"description":null,"campaignID":"789934082","trackingID":"202003_5e6fa18a87853a69eb306910","industry":null,"active":"1","isQualified":"1","isContact":"1","isCustomer":"1","status":"4","updateTimestamp":"2020-05-08 20:24:48","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 resultSet = JSON.parse(obj);
}

Answer 1

Taking a look at the problem:

function test(){
 var obj={"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":"email@here.com","website":null,"phoneNumber":null,"officePhoneNumber":null,"phoneNumberExtension":null,"mobilePhoneNumber":null,"faxNumber":null,"description":null,"campaignID":"789934082","trackingID":"202003_5e6fa18a87853a69eb306910","industry":null,"active":"1","isQualified":"1","isContact":"1","isCustomer":"1","status":"4","updateTimestamp":"2020-05-08 20:24:48","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 resultSet = JSON.parse(JSON.stringify(obj));
}

but so what the point of the parse is to return an object from a string not from object.

But I do see the problem. 'Cannot connect to the server'

I found that this does seem to work know:

function test(){
 var obj='{"result":{"lead":[{"id":"332","accountID":"","ownerID":"","companyName":"","title":"","firstName":"RYAN","lastName":"CAVANAUGH","street":"","city":"","country":"","state":"","zipcode":"","emailAddress":"email@here.com","website":"","phoneNumber":"","officePhoneNumber":"","phoneNumberExtension":"","mobilePhoneNumber":"","faxNumber":"","description":"","campaignID":"789934082","trackingID":"202003_5e6fa18a87853a69eb306910","industry":"","active":"1","isQualified":"1","isContact":"1","isCustomer":"1","status":"4","updateTimestamp":"2020-05-08 20:24:48","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 resultSet = JSON.parse(obj);
 var end="is near";//I just put this here to have a place to stop with debugger running
}

I replaced all of the null s with "".
