Hi @Frank_Hassanabad,

This morning I decided to install ELK 7.9.1 and all beats from scratch. This is a clean installation. I just setup Auditbeat and Heartbeat to test Uptime and Security. Uptime is displaying the error "`Internal Server Error`" and Security is displaying the error "`Data Fetch Failure`", and when click on "`See the full error(s)`" you can see the know error that we were talking about from the start.

 ![visualization error 2](https://us1.discourse-cdn.com/elastic/original/3X/e/5/e59c05599afa8d62cfb27a18a33befa6e84b5fb9.png)

Not sure where the root issue is, but after importing the index template (either with `setup` or manually with `curl`) I can see the mappings seems to be right, but then data is being indexed apparently with errors, causing Uptime and Security can't work properly.

This issue started after I upgraded to ELK 7.9.1 and upgraded the beats to match same version. Could this be a bug on this version?

If you have more ideas or steps for troubleshooting, please help me.

Thank you
