When I try to run an anomaly detection job in elastic I get an error and it does not execute me. The error I get in the elastic console is this:

Does the following directory exist on your machine?

If it doesn't then please create it, making sure it's owned and writable by the user that Elasticsearch is running as.

The docs on how to prevent this issue happening again are in Temp directory | Elasticsearch Guide [7.8] | Elastic.
