Scripted RREST API payload need to get for invalid JSON

[Pavan_Snow_1]

I have a scripted REST api and now I am trying to get the payload if it is a valid then I am able to get it as below

var payload = request.body.data;

But if third party system send invalid JSON to ServiceNow then how to capture that I have tried different ways but not able to get it.

Below is the example of invalid JSON but I am trying to get it. 

{
	"Data": {
		"Name": "test",
		"ID": "1500"
		"description": "Test description"
	}
}

 Share any solution if it is possible to get in any way.

Thanks in advance!

In the catch block you can do as below:

catch(ex){

var res = {};
res["status"] = "Error";
res["message"] = ex.message;
res["Payload"] =  request.body.data;
response.setBody(JSON.stringify(res)); // sending the invalid message back

}

Hi @Prince Arora ,

request.body.data;

 It is not working.

@Pavan_Snow_1 ,

Yes, it should not work since we cannot assign an invalid response to a variable.

The behaviour is correct!

In general, if we take REST API as an example, whenever we do not receive a valid response from API, we will receive the error message, status code, but not the content of the response, so you can proceed with only the status and error messages. You can check examples on google for more info.

Hi @Pavan_Snow_1 ,

you can use something like below

var req = request.body.dataString;
var body = JSON.parse(req);
try{
var data = JSON.parse(body); 
}
catch(e){
    gs.log("JSON Error "+e);
}

if(data != undefined){
//do what you need with payload
}

Hi @Kamil Smusz ,

See below error

com.glide.rest.util.RESTRuntimeException: The payload is not valid JSON.

I am getting when it is invalid JSON. Errors are okay but I am trying to capture that invalid payload on the transaction record.
