Custom Property update in coding - throws AccessDeniedException

Question

Hi,
I am using the following code to update the newly created custom property in KM
RID rid1 = RID.getRID("/documents/MWRD/internet/Departments/Engineering/Engineering_Reports/Reports/"+res.getDisplayName());
IResource fileResource = ResourceFactory.getInstance().getResource(rid1, context);
IPropertyName propName = new PropertyName("http://mwrd/xmlns/propertiesnamespace","DepartmentName");
IProperty property = fileResource.getProperty(propName);
if(property == null){
property = new Property(propName,"Engineeringreports");
fileResource.setProperty(property);
During the execution of the line set property following error is displayed "AccessDeniedExceptionPermission denied: uri=/documents/Engineering/Engineering_Reports/Reports/10-2008-Excessive_Infiltration_Vol_36.pdf, permission=leaf_write_properties, user=anonymous
Please help me to solve the issue

Yes The code was modified to handle version issues
IVersionController vc = (IVersionController) folderResource.as(IVersionController.class);
     IResourceList rc = folderResource.getChildren();                    
     if (vc != null){vc.disable(true);};
          fileResource.setProperty(mutableProperty);
     if (vc != null){vc.enable(rc);};
