Hey all Today when navigating to the fleet page I was welcomed with an error - Cannot read properties of undefined (reading 'preserve\_original\_event') No changes were made to any of our integrations and we have not set 'preserve\_original\_event' on any of them. At this time we have 1pass and cloudflare integrations configured on 7.16.3 Any help would be appreciated. ---

Hi! This error was [fixed](https://github.com/elastic/kibana/pull/124482) in 7.17.1 in Fleet UI, could you try upgrading the stack? ---
