After updating attack signatures, a Signature-system called "IBM WebSphere" may be created that does not contain a REST ID, and BIG-IQ will fail discovery. If you look at the REST output for this item at https://bigip_address/mgmt/tm/asm/signature-systems/ and look for "IBM WebSphere", you will see that the id field is empty.
BIG-IQ discovery fails.
This can occur when updating attack signatures, and when using BIG-IQ discovery.
On the affected device run the following: perl -MF5::Utils::Rest -MF5::DbUtils -MF5::ASMConfig::Entity::SignatureSystem -e "F5::Utils::Rest::populate_uuids(dbh => F5::DbUtils::get_dbh(), rest_entities => ['F5::ASMConfig::Entity::SignatureSystem'])"
None
