Cause
The issue occurred when the customer had more than 112 User Attributes. The number of attributes in this case exceeded the WildFly application server default maximum parameters threshold of 1000
Workaround
You can manually edit the file aveksa-standalone-full.xml located under /home/oracle/wildfly/standalone/configuration and add the max-parameters and set it to 3000 instead of the default (1000) as below

In the example below the limit is increased from 1000 (default) to 3000 by adding the max-parameters value and setting it to 3000. 
acm-710:/home/oracle/wildfly/standalone/configuration # cat aveksa-standalone-full.xml | grep listener
                <http-acceptor name="http-acceptor" http-listener="default"/>
                <http-acceptor name="http-acceptor-throughput" http-listener="default">
                <http-listener name="default" socket-binding="http" max-post-size="2147483647" redirect-socket="https" enable-http2="true" max-parameters="3000"/>
                <https-listener name="https" socket-binding="https" max-post-size="2147483647" security-realm="AveksaRealm" enabled-protocols="TLSv1,TLSv1.1,TLSv1.2" max-parameters="3000"/>
                <https-listener name="agent-ssl" socket-binding="agent-ssl" max-post-size="2147483647" security-realm="AveksaAgentRealm" verify-client="REQUIRED" enabled-protocols="TLSv1.2" max-parameters="3000"/>
