Hi Team,
As we know Form API is deprecated from ACS common 6.0.0, In our project we used form API and we replaced with the ACS common Form custom classes instead directly refer acs common.
It is working fine in author and publisher with authentication, but it is not working for the anonymous user.
We debugged it and found the issue that service user "acs-commons-form-helper-service" removed from
bundle/src/main/java/com/adobe/acs/commons/users/impl/ProtectedAuthorizables.java
content/src/main/content/jcr_root/apps/acs-commons/config/org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended-acs-commons.config
I have tried to add the same service user using below approach still got the same error
org.apache.sling.api.resource.PersistenceException: Resource at '/content/test/jcr:content/par/canvas_2096355623/canvas_par/gridcolumn/1/start' is not modifiable.

Is anyone face the similar kind of issue after upgrade latest acs common.
