Hi–
In my graylog server logs, I see this error being continuously streamed:
2019-11-10T12:26:21.373-08:00 ERROR [EventNotificationExecutionJob] Couldn’t find event definition with ID \<5dae52f29571ee0ba720c011\>.

How can I resolve that? Thanks.

What do you think if you read the error message?

Hi–
Because this is a continuous stream, there is something that needs to be fixed, however, I don’t know what is and that is what I am asking for assistance for. I have not found a reference to job 5d5991cd9571ee33ecd51dde which is the only constant in the stream. Any assistance? Thanks.

how many events have you defined? I guess you might have worked directly on the MongoDB Database or imported some content packs?
I would delete all events and check if this error is still given and if yes, check the mongoDB
