Evaluation of error message table API

[danielrueckert]

Hello everyone,

I am currently familiarising myself a little with the subject of interfaces. I currently have an interface that creates an incident in another instance.

Instance 1 - Trigger Interface to post incident in Instance 2

The interface is also running smoothly. However, I am currently stuck with error handling.

With the variable

var resp = new JSONParser().parse(r.execute().getBody()).result;

I read the response of the interface and convert it back into javascript.
In the event of an error, I receive the response:

{

"error":{

   "message": "Operation Failed",

   "detail": "Operation against file 'incident' was aborted by Business Rule 'Abort changes on    

   group^e915f3b193870210a38a76718bba10dc'. Business Rule Stack:Abort changes on group"

   },

"status": "failure"

}

I would like to write the detail from this to the log. And try this with the variable

var responseIfError = resp.detail;

to read it out. However, the variable gets the value undefined.

When the interface runs through without errors, I read the incident number and system_id in the same way, which works without any problems.

var incidentID = resp.number;
var sysID = resp.sys_id;

Response shortened:

{

"result": {

   "parent":"",

   "made_sla":"true",

   "caused_by":"",

   "watch_list":"",

   "upon_reject":"cancel",

   "sys_updated_on":"2024-06-28 07:09:36",

   "child_incidents":"0",

   "hold_reason":"",

   "origin_table":"",

   "task_effective_number":"INC0010081",

   "approval_history":"",

   "number":"INC0010081",

   "sys_id":"0f73be3193430210a38a76718bba100c"

   }

}

Can you help me here and point out my error?

Thank you very much

I think you need to use resp.error.detail instead of resp.detail

Unfortunately it does not work.

Thanks anyway

I have added the response in case of success.

That's because you go straight to the "result" property in this line of your code:

var resp = new JSONParser().parse(r.execute().getBody()).result;

But in case of an error, the top-level node of the response is called "error" and not "result". Hence the undefined value.

If you change the line above to this:

var resp = new JSONParser().parse(r.execute().getBody());

you should be able to retrieve the necessary information as follows:

// Traverse the "result" property in case of success
var incidentID = resp.result.number;
var sysID = resp.result.sys_id;

// Traverse the "error" property in case of error
var responseIfError = resp.error.detail;

It works. Thank you very much.👍
