[JENKINS-58966] httprequest plugin response does not include content in case http request fails with error 500

Code below is using 'validResponseCodes' to prevent http request to throw exception in case service returns error 500.

def cusHeader = [[name: 'Content-Type', value: 'application/json; charset=utf-8'],[name: 'Accept-Charset', value: 'utf-8']] 


def payload = "{\"body\":{\"ProcessName\":\"Generic Process\"}}"

def response = httpRequest timeout: 60, authentication: "${JENKINS_APP_CRED}", customHeaders: cusHeader, httpMode: 'POST', requestBody: payload, url: "http://${rest_serv}:9001/RunProcess", validResponseCodes: '100:500'



println response

 

Although we get along with code 500 a json with error message, it is not included in response from httprequest as we can see below:

Result from curl:
