Publish - Access denied - Unable to commit changes to session

Hi,

 

I am using AEM Cloud, and trying to commit a created resource in the `createResource` method below.

 

 

    @Model(
            adaptables = {Resource.class, SlingHttpServletRequest.class},
            adapters = {ArticleModel.class, ComponentExporter.class},
            resourceType = ArticleModel.RESOURCE_TYPE,
            defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
    public class ArticleModel extends AbstractComponentImpl {

        @inject public SlingHttpServletRequest request;

        @SlingObject private ResourceResolver resourceResolver;

        @PostConstruct
        private void init() throws Exception {
            createResource();
        }

        public void createResource() throws Exception {

            String path = request.getResource().getPath();
            String newResourceName = "embed2";
            Resource parentResource = resourceResolver.getResource(path);

            Map<String, Object> properties = new HashMap<>();
            properties.put("jcr:primaryType", "nt:unstructured");
            properties.put("sling:resourceType", "mysite/components/embed");
            properties.put("type", "embeddable");
            properties.put(
                    "embeddableResourceType", "core/wcm/components/embed/v1/embed/embeddable/youtube");

            try {
                Resource newResource =
                        resourceResolver.create(parentResource, newResourceName, properties);
                resourceResolver.commit();
            } catch (PersistenceException e) {
                throw new Exception("Error while creating new resource: " + e.getMessage(), e);
            }
        }
    }

 

 

This works on my local Author instance, but when I view my page on Publish, I get the following error message:

My situation is similar to this solution, where he went into the CRX and configMgr to create a system user and used a `resourceResolverFactory` to get the resolver.

But although his solution works on a local Publish instance, I cannot create an user on an instance deployed to Cloud AEM as I don't have access to CRX and configMgr there.

What would be the proper solution in this case?
 
Thank you,

You already attached the standard solution for this use case. You need to get ResourceResolver for a user and that user should have proper permissions to perform read/write in JCR.

Regarding permissions, I would recommend you to talk to the operations team or product own (who supposed to have access to the relevant console).

Publish instance is read-only for AEMaaCS. 

All edits/updates should happen on author and replicated to publish.
