How to catch an Error of a Scriptrunner post function on Jira Cloud?

[Riccardo Micozzi]

Hi,

I'm using a ScriptRunner post function that get the value of a CustomField(text read only) and parse this String in a Json and after that read the content of the Json and do something(it Works).

The problem is when in the customfield is passed a String that is not in the correct format(Json), for example if there isn't the first { or the last } of the Json, in this case the post function Failed and i Get this error:

2021-01-20 09:10:42.847 ERROR - expecting a ',' or a ']',  but got 
the current character of  ':' with an int value of 58  on array index of 1 


The current character read is ':' with an int value of 58
expecting a ',' or a ']',  but got 
the current character of  ':' with an int value of 58  on array index of 1 

line number 1
index number 5
["id":"DefectD1","tipologia":"Consegna","descrizione":"defect"} , {"id":"DefectD1","tipologia":"Installazione","descrizione":"defect"}]
.....^

The part of the Code that Parse the String in the Json is this: 

String jsonStr = listaAttributiD 
def res = (new JsonSlurper().parseText(jsonStr)) as Map   //HERE IS WHERE THE ERROR LOADS

 There is a way to catch this error and prevent the failed of the Post Function?

Thanks

Hi Ricardo,

I can confirm that ScriptRunner for Jira Cloud uses Groovy so this means you would need to the standard approach in groovy to catch exceptions.

This would mean that you write a try/catch statment in your code in order to handle when the operation fails and in the catch statement if it does you could log a stagement to say it failed or just return so the script does not continue.

I can confirm the page located here explains how try/catch statments work in groovy and you wll be able to use this as a reference gudie to helo to refactor your script.

Regards,

Kristian

Hello @Riccardo Micozzi 

You can do a try and catch for theses line, it will be something like this :

https://www.tutorialspoint.com/groovy/groovy_exception_handling.htm

try {

String jsonStr = listaAttributiD 
def res = (new JsonSlurper().parseText(jsonStr)) as Map

} catch (Error) // not sure about if i can catch the ERROR {

your instruction here}

I'm not a groovy expert but i already implemented something like this for one client.

Hope this helps
