Facing similar issue as posted in Unable to login to Camunda after upgrading to 7.21.
Error - java.lang.NullPointerException: Cannot invoke “org.camunda.bpm.webapp.impl.security.auth.UserAuthentication.getProcessEngineName()” because “authentication” is null
Previously used -
var authentications = Authentications.getFromSession(request.getSession());
if (authentications != null) {
var authentication = authentications.getAuthenticationForProcessEngine(processEngine.getName());
Currently changed to -
var authentications = AuthenticationUtil.getAuthsFromSession(request.getSession());
if (authentications != null) {
var authentication = authentications.getAuthenticationForProcessEngine(processEngine.getName());
Any help would be really great.
