How to handle response of more than 4000 characters using camunda external task

[aravindhrs]

@Ankur_Rathi You need to pass that variable as Object.

You can JSON stringify that object and pass the type json to the process.

{
    "variables": {
        "aVariablename": {
            "value": "<Serialized Json variable value>",
            "type": "Json"
        }
    }
}

And when retrieving that variable use deserializeValues=false to get the json object value

Error while starting process instance

@Sandeep_Yalamarthi you’re storing the payload as json string in the process variable. But the payload size exceeds varchar(4000), so it fails with exception was aborted: ERROR: value too long for type character varying(4000) Call getNextException to see other errors in the batch. Alternatively, you can store this payload as an object.
