Hi @sachinty - can you post the stack trace from the logs? This should tell you a little more. This error could be due to a few things, may be on the DB side or with bad data. Is this a new connector or was this previously working and then the issue arose?
yes correct, can you share the log trace here ?? and also, is it the first time you are running the aggregation for the application?? or it was working earlier and now you are facing the error??
