Export Rules -- Getting BAD request

[Detlef (Detlef Wolf)]

I'm trying to extract my created detection rules.

From my python script I receive the following debug messages:

2022-02-02 17:57:22,916 __main__     ERROR    An exception occurred while processing export rules request

I already tried without any parameter, but the error remains the same.

Hi @Detlef , as I mentioned on the community slack, it looks like you haven't added a kbn-xsrf header, which is needed for any API call to Kibana.

That was the trick.
