问题
I have written a python script to just compare to strings and putting attribute in the flowfile. But while handling exceptions, I am getting below error always and my flowfile is stuck in the queue with ExecuteScript Processor with below exception:

****The below is the script:****
enter code here
import java
import os
from java.sql import SQLException
from java.lang import Throwable
flowFile = None
try:
flowFile = session.get()
if flowFile != None:
originalFilname = flowFile.getAttribute('sourceFileName')
pathFileNameEntity = originalFilname.rsplit('_', 1)[0]
fileNameEntity = pathFileNameEntity.rsplit('/', 1)[-1]
realTimeEntityString = \
flowFile.getAttribute('my.entity.name')
for entityName in realTimeEntityString.split(','):
ename = 'rr_' + entityName.lower()
if ename == fileNameEntity.lower():
cEntityName = entityName
flowFile = session.putAttribute(flowFile,
'current.entity.ename', str(cEntityName))
session.transfer(flowFile, REL_SUCCESS)
else:
flowFile = session.putAttribute(flowFile, 'errorMessage'
, 'Issue with RT Entity Names')
session.transfer(flowFile, REL_FAILURE)
except Exception, e:
if flowFile != None:
flowFile = session.putAttribute(flowFile, 'errorMessage',
str(e))
session.transfer(flowFile, REL_FAILURE)
except Throwable, e:
if flowFile != None:
flowFile = session.putAttribute(flowFile, 'errorMessage',
str(e))
session.transfer(flowFile, REL_FAILURE)
Can anybody help me understand why it is failing going into except block even if exception did not occur. Is it Syntax error?
