Hi, all.
I used the delegation identity provider whit github, it run ok, and authorized my account in cas success.
But the console log occured a problem as below(tikets registry into redis)
2023-07-25 16:30:00,815 ERROR [org.apereo.cas.util.serialization.AbstractJacksonBackedStringSerializer] - <Cannot read/parse [{"@class":"org.apereo.cas.ticket.TicketGrantingTicketImpl","@id":1,"id":"TGT-6-********6aWWgwVDXEIgNLDA-nKZLV...] to deserialize into type [class org.apereo.cas.ticket.TicketGrantingTicketImpl]. This may be caused in the absence of a configuration/support module that knows how to interpret the fragment, specially if the fragment describes a CAS registered service definition.
