Groovy code error - Rest Post to API (RTDM SAS PROC)

[RTDM_User]

HI,

HELP needed with java.lang.NullPointerException ERROR,

I’m trying to run the code below (i have imported all the necessary packages) - 

def slurper = new groovy.json.JsonSlurper()

def result = slurper.parseText('{"name":["itay","omer","shlomi","rotem"],"age":30}')

def client = new RESTClient( 'http://localhost:3000' )

writeToFile("JSON REQ1")

writeToFile(result)

def resp = client.post( path : '/testrtdm',

ContentType: JSON,

body: result,

and getting error without any explanation –

HI,

This problem appears to be caused by incorrect use of the groovy library RESTClient. I dont have a great deal of exposure to that, perhaps a post on a groovy coding forum will yield better results.

Cheers

Hi james and thank you for answering,

I don’t think that the use of RESTClient causing the error because before the current POST method I’ve tried and succeed with get method (called the api and got the json response).

I assume that I don’t have the correct syntax for activating the POST method.

Do you have an example of post rest via groovy?

Tnx, Itay.
