org.graylog.events.processor.aggregation.PivotAggregationSearch - Removing non-existing streams

getting this error in graylog but i am not able to replicate this issue?

  • what graylog version?
  • what did you do befoe that error?
  • where did you get the error?

be a little more verbose and you might get help.

i find out that it was some event which is created in alert with wrong stream that’s why i was facing this issue
