Simple REST endpoint not working

[Mouna Hammoudi]

I am trying to perform a REST endpoint with its corresponding web fragment but I am getting the error: script function failed on issue: issue: SF-347, user: mouh, fieldId: __init__, file: <inline script>, edit behaviour: https://itrac-dev.eur.ad.sag/plugins/servlet/scriptrunner/admin/behaviours/edit/8, https://itrac-dev.eur.ad.sag/plugins/servlet/scriptrunner/admin/behaviours/edit/17, https://itrac-dev.eur.ad.sag/plugins/servlet/scriptrunner/admin/behaviours/edit/21

Here is my error log here below:

 I don't understand why I have this error my code is super simple. Here is the way in which I have created my web fragment: 

This is a screenshot of the custom web item fragment I have created: 

This is the corresponding REST endpoint I have created: 

I am specifying the file MounaBulkSummary.groovy to be the one containing the code for the REST endpoint. 

Here is the content of the file MounaBulkSummary.groovy

import groovy.transform.BaseScript

def log = Logger.warn("atlassian-jira.log")

    def baseUrl = ScriptRunnerImpl.getOsgiService(ApplicationProperties).getBaseUrl(UrlMode.ABSOLUTE)

    def redirectUrl = "https://secapps.eur.ad.sag:9888/FPIA/?iTrac=${issue.key}&reporter=${user.key}&baseURL=${baseUrl}"

    Response.temporaryRedirect(URI.create(redirectUrl)).build()
