Tagmanager.resolve all returns null on AEM 6.5 publish instance

Hi,

 

I am facing an issue where the Tags are not being resolved on AEM 6.5 publish instance.

 

The following code is being used to resolve the tag

final TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
final Tag tag = tagManager.resolve("/content/cq:tags/abc");

On AEM Author, tags are resolved correctly, but the same code is returning null on publish instance.

 

The things which I have checked on publish instance:

1. Tags are available on publish instance

2. service user used for resolving the tags is available on publish instance

3. read and write permissions are provided for /content/cq:tags

 

Please let me know if there is anything else that needs to be checked.

I tired getting the resource of the tag using the path using the below code and the tagResource is null. 

resourceResolver = getResolver.getServiceResolver(); Resource tagResource = resourceResolver.getResource(tagResource);

The service user is unable to get the tag resource.


Hi @smrithigo 
Could you please check logs, seems your service user is not correct bind with your bundle.

check the Service Mappings:

@Reference private ResourceResolverFactory resolverFactory; @Activate public void doSomething(ComponentContext ctx) { Map<String, Object> param = new HashMap<String, Object>(); param.put(ResourceResolverFactory.SUBSERVICE, "read-service"); ResourceResolver resolver = null; try { resolver = resolverFactory.getServiceResourceResolver(param);

@smrithigo ,

 

You are already doing the basic checks that needed to be done to debug this issue. Maybe to further debug this you can try the following:

1) Confirm tagManager object is not null

2) Check what is the path that is being passed as parameter in the resolve(). Print that path in the logs or use breakpoints if the debugging is done in local machine.

3) Double check that the service user used to read/write the tags has read permission to the "/content/cq:tags/abc" path.

 

Hope this helps.

    Thank you for you response. Please find my answers:

     

    1. yes, tagmanager is not null

    2. the page is /content/cq:tags/abc (it is basically the namespace created for the proejct). I am not passing the tagID, instead the path of the tag.

    3. Yes, service user has both read and write permissions on publish. i tired by giving all the permission to see if I am missing something. But still it is throwing null.

      I see. Is the /content/cq:tags/abc has the jcr:primaryType as cq:Tag?

        Hi @smrithigo 
        Does it works in your local or any of the AEM instance.

         

        Could you try to publish tags and try below servlet in your local : https://github.com/arunpatidar02/aem63app-repo/blob/master/java/GetTags.java 

        This is the working & tested example.

          Hi @arunpatidar ,

          Thank you for sharing this code.

           

          I have tested it on my publish instance and I can see that the servlet is returning the tag titles. This is the result that I got.

           

          Hat Tag details(Content) Hat

          Hat Tag details(etc) Hat

           

          here you have created the tagmanager object as below:

          TagManager tagManager = req.getResourceResolver().adaptTo(TagManager.class);

          I am trying to get the tagmanager object using the custom service user. And i think it has something to do with the permissions. But I have tried giving all the permissions for the service users on publish, but still not working.
