[cobbler] custom cobbler signature

[Malantonio, John]

Hello,

I am trying to modify distro_signatures.json for a new SLES 15 OS but not having luck. I
have added sles 12 sp3 with no issue. Even after adding the below section and restarting
cobblerd I still receive "ERROR | No signature matched in
/var/www/cobbler/ks_mirror/sles15-x86_64"  Any suggestion on troubleshooting?

Cobbler on CentOS7
Cobbler Version 2.8.2

   "sles15": {
    "signatures":["suse"],
    "version_file":"(sles|SLES-for-VMware)-release-15-(.*).rpm",
    "version_file_regex":null,
    "kernel_arch":"kernel-(.*)\\.rpm",
    "kernel_arch_regex":null,
    "supported_arches":["x86_64"],
    "supported_repo_breeds":["yum"],
    "kernel_file":"linux[64.gz]?",
    "initrd_file":"initrd[64]?",
    "isolinux_ok":false,
   
"default_kickstart":"/var/lib/cobbler/kickstarts/sample_autoyast.xml",
    "kernel_options":"install=$tree",
    "kernel_options_post":"",
    "boot_files":[]
   }
