AEM 6.3.3 | Error while saving using session.save()

What kind of node are you trying to save ?

@Veena_07

I have created user via createuser method (i.e. UserManager ("The Adobe AEM Quickstart and Web Application.") ).

then setting user properties.

Does that mean even the system user creation is done programmatically here ? If so , did you use createUser method or createSystemUser ?

Veena_07,

I have implemented Registration functionality which is Servlet that gets data from form.

Based, on that data i createUser via code taking session via systemuser.

Can you provide the code snippet which is throwing the error ? I will try it in my local and let you know if I am also facing the issue , if so will try to figure out a solution. Also please let us know the AEM version

I have given full permission to my system user:

That's strange. But the only explanation for this exception are insufficient permissions of the service owning that session. Just to eliminate all other reasons, can you temporarily switch to an admin user and try that?

Are you saying yo use login.adminstrative() method.
