Hi,

I am not able to parameterize Post method HTTP body. I am getting following error

Katalon version 5.60

**Script:**

println(authcode)

WebUI.closeBrowser()

def response = WS.sendRequest(findTestObject(‘postAuthCode’), [(‘code’), authcode])

println(response.responseText)

WS.verifyResponseStatusCode(response, ‘200’)

**Console Log:**

i think call should be:

```auto
def response = WS.sendRequest(findTestObject('postAuthCode', [('code'): authcode]))

```
