Hi Team, I'm trying to implement a counter using state in Jython and Im getting this error please help me with this.

init script : state['record_counter'] = 0

script: try: for record in records: state['record_counter'] += 1 record.value['record_id'] = state['record_counter'] record.value['version'] = 1
output.write(record) except Exception as e: error.write(record, e.message)

Error Trace:

Update your question and include your Jython code in it.

Initially I configured the pipeline Error records to be discarded. and I saw the stack trace is due to $Err.write. So I removed the error.write from script and replaced it with Now no errors but jython is not giving any output too.. This is cloud streamsets, I don't know where to find logs

Did you see my side note above? "make sure try... except is within for... records loop and not the other way around." -- The reason why it was failing before you removed "error.write" is because there's no reference to "record" *outside* of for... records loop. Does that make sense?

Yes I got that.. Thanks

It works for me in SDC 3.5.2 and 3.6.0. What version of SDC are you running? And, is this all the code you have in your Jython Eval? BTW, side note: make sure try... except is within for... records loop and not the other way around.
