Hi Prakash,
I had the same issue when upgrading CAS from 6.6 to 7.3 with AWS
Elasticache Redis.
This has been solved by adding the following property:
cas.ticket.registry.redis.enable-redis-search=false
I’m not sure if there is a better solution but it worked for me, although I
have not performed any performance test yet, so, I’m not yet sure if there
will be any performance impact.
Thanks.

I am trying to integrate Redis Ticket Registry for CAS 7.2.4. And I ran
into following error while running my CAS
*Caused by: org.springframework.beans.factory.BeanCreationException: Error

[org/apereo/cas/config/CasRedisTicketRegistryAutoConfiguration$RedisTicketRegistryModulesConfiguration.class]:
Failed to instantiate [org.apereo.cas.redis.core.RedisModulesOperations]:
Factory method 'redisModulesOperations' threw exception with message: Redis

The issue seem to arise from following block of code of class
'CasRedisTicketRegistryAutoConfiguration':
val operations = redisModulesOperations.stream().filter(BeanSupplier::
isNotProxy).findFirst();
return new RedisTicketRegistry(cipher, ticketSerializationManager,
ticketCatalog, applicationContext,
casRedisTemplates, redisTicketRegistryCache,
redisTicketRegistryMessagePublisher,
operations, redisKeyGeneratorFactory, adapter, casProperties);
The config is:
cas:
ticket:
registry:
redis:
# Redis server host
host: "localhost"
port: 6379
password: "your-redis-password"
database: 0
enabled: true
crypto:
enabled: true
encryption:
key: "YourEncryptionKeyMustBeAtLeast256Bits"
signing:
key: "YourSigningKeyMustBeAtLeast256Bits"
I have added following dependencies:
implementation("org.apereo.cas:cas-server-support-redis-ticket-registry:${
project.'cas.version'}")
implementation("org.apereo.cas:cas-server-support-redis-modules:${project.
'cas.version'}")
