When configuring xray-url only, without the url - the audit command didn't recognize them, and couldn't set JAS scanners:

I keep getting this warning “To include 'Advanced Security' scan as part of the audit output, please run the 'jf c add' command before running this command.“ when running the jf audit.

The command I use to reproduce the issue:
jf c add "test" --xray-url="PLATFORM_URL" --interactive=false --access-token="access-token*****"

I was able to solve it using the following cmd:
jf c add "test" --url="PLATFORM_URL" --interactive=false --access-token="access-token******"

@hadarshjfrog I think it's worth adding a test to audit_test.go - configure a server with Xray URL only and validate we get JAS results
