Hi @sateesh , thanks for your response
Was able to fix after giving the correct ctx syntax
I was following your answer and i got stuck at showing the message, so i proceeded succesfully until step 5 wich does not show me the filed i am interested in (_source.SOURCE_ADDRESS)
My query looks similar to yours and i can’t find what my issue is… Please see the screeen-shots attached, can you point me what i have missed?
LATER EDIT: Acctually it work, beacuse of the big output it was not showing, but when i send the message as a test it works.
Sorry and thanks again!
