Error: Failed to decrypt report job data. Please re-generate this report.

Hi Mjay,

Can you please check if you have set youxpack.reporting.encryptionKey setting in Kibana.yml? If you haven't set it and kibana is restarted - you can get this error.

Let us know?

Thanks,
Bhavya

Yes. I have set it and is working. But independently it works, when integrated with watcher it is not working.
