Elastic Stack Kibana

Not able to concatenating two string fields in kibana using the painless script, having a very large string. My scripts are as follow :-:
'''
if (doc['ERROR'].size() != 0 && doc['ABORT'].size() != 0 && doc['FAIL'].size()!=0 && doc['STATUS 502'].size()!=0) {
'<<<Error'+doc['ERROR'].value+'>>><<Fail:'+doc['FAIL'].value+'>><<Abort:'+doc['ABORT'].value+'>><<<STATUS 502:'+doc['STATUS 502'].value+'>>>'
}else{
"No Desciption"
}
'''
here Error field data is too long so in scripted field result not able to concatenate. and when i further investigate it doc['field'].size() return null value.
