hi I have this configurartion of emailext in the jenkinsfile

 
emailext body: emailContent(env.global_exception),
                    subject: "[Jenkins] ${jobName}",
                    to: "${mailRecipients}",
 
for the email ext plugin and this call that called emailContent.grooby
 
def call(global_exception) {
  return '''
  -------------------------------------------------------------------------------
  Build ${ENV,var="JOB_NAME"} #${BUILD_NUMBER} ${BUILD_STATUS}
  URL: ${BUILD_URL}
  -------------------------------------------------------------------------------
  Changes:
  ${CHANGES}
  -------------------------------------------------------------------------------
  Error:
  '''+
  global_exception + "
n" +
  '''
  -------------------------------------------------------------------------------
  Failed Tests:
  ${FAILED_TESTS,maxTests=500,showMessage=false,showStack=false}
  -------------------------------------------------------------------------------
  For complete test report and logs see https://nightlies.apache.org/cassandra/${JOB_NAME}/${BUILD_NUMBER}/
  '''
}
I am trying to paste the call in the pipeline and it parsing it correctly
 
 
but in the mail that jenkins create I get one line of this message
