Hi, In our project we have "n" number of nodes which does not have sling:resourceType and it's caussing below error in logs.org.apache.sling.servlets.get.impl.DefaultGetServlet No renderer for extension html, cannot render resource JcrNodeResource, type=nt:unstructured, superType=null. Please suggest how can we handle this.
Solved! Go to Solution.

Hi @vijitha - you can write something like - if you have list of nodes, you can create an array of it or you can read it from csv
import javax.jcr.Node
import javax.jcr.Session
// Array of node paths to delete
def pathsToDelete = [
"/content/company/language/en/home/jcr:content/root/responsivegrid/text",
"/content/company/language/en/home/jcr:content/root/responsivegrid/text/test",
"/content/company/language/en/support/jcr:content/root/responsivegrid/image",
"/content/company/language/en/build/jcr:content/root/responsivegrid/cta"
]
// Get the current session
def session = resourceResolver.adaptTo(Session)
// Loop through the paths and delete the nodes
pathsToDelete.each { path ->
Node node = session.getNode(path)
node.remove()
}
// Save the changes to the session
session.save()
It can be done by using Node API.
You can right a servlet to pass the parent node path on temporary basis. Later, this servlet can be removed from code repo.
First a parent node path would be required and then all child nodes can be iterated using node api.
Then, you can check if the node has sling:resourceType property or not. If it's not there, you can remove it.
Here, is one similar thread.
I hope it helps.
Hi Rohit,
Thanks for your reply.I have simliar issue for "n" number of nodes.How can we give parent node path for this.
Few Examples:
/content/company/language/en/home/jcr:content/root/responsivegrid/text ---I need to delete text node for this
/content/company/language/en/home/jcr:content/root/responsivegrid/text/test---I need to delete test node for this
/content/company/language/en/support/jcr:content/root/responsivegrid/image---I need to delete image node for this
/content/company/language/en/build/jcr:content/root/responsivegrid/cta---I need to delete cta node for this

// Loop through the paths and delete the nodes
pathsToDelete.each { path ->
Node node = session.getNode(path)
node.remove()
}
// Save the changes to the session
session.save()
Thank you @Nitin_laad
It worked for me.

Hello @vijitha
It can be done via Groovy script.
1. You would need to traverse the pages and configured components hierarchically.
2. Check if the sling:resourceType exists. If not, delete the node.
You would have to append /apps to sling:resourceType to check for existence. A similar script for visiting sling:resourceType is shared on SOLVED: Find all the components on the current pag... - Adobe Experience League Community - 577223
Hello @vijitha ,
To delete the node which doesn't have sling:resourceType you can run query builder. Here is a sample query builder ->
path=/content/company/language/en
type=nt:unstructured
1_property=sling:resourceType
1_property.operation=not
2_property=jcr:created
2_property.operation=exists
p.limit=-1
2_property is added to find out the component. Otherwise, it will remove all the nodes.
Once you get the list run a loop and resolve to Node type and delete.
Deleting node from Java will be like
// RUN querybuilder code
String rootPath = "/content/company/language/en";
ResourceResolver resourceResolver = getRequest().getResourceResolver();
Node rootNode = resourceResolver.resolve(rootPath).adaptTo(Node.class);
//Iterate over querybuilder result and get the PATH
Node faultyNode = rootNode.getNode(PATH.replace(rootPath, ""));
faultyNode.remove();
// Loop Scope end
rootNode.getSession().save();
Hope it will help you.
Hi @Sady_Rifat
Thanks for your reply I have tried with your query in local It's working fine but in higher envronaments I don't see 2_property=jcr:created node in my code base.
I see only cq:lastRolledoutBy and cq:lastRolledout properties for /content/company/language/en/home/jcr:content/root/responsivegrid/text so I am not able to get the exact results.
So, if you use 2_property=cq:lastRolledoutBy or 2_property=cq:lastRolledout, this should work as expected. Aren't you?
I have tried that but it's not giving the exact results.
Ex:/content/company/language/en/home/jcr:content/root/responsivegrid/text
/content/company/language/en/home/jcr:content/root/responsivegrid/text/cq:responsive
To delete unwanted nodes you can follow below steps
1. Identify the nodes using the querybuilder and list out all the possible node paths and export them to the Excel.
2. Install groovy console in the instance and give required permission to the user to run the script
3. Upload the excel in your DAM location and point that in your groovy script
4. Run the script with dry run flag and check using print method in groovy that all the nodes are iterated properly.
5. Then enable actual run and execute the script.
Below is the link which provides the details of groovy and you can see some samples as well in the console dashboard
Groovy console Link:

with script https://dileepakv.blogspot.com/2017/12/bulk-delete-and-package-paths-in-aem.html
Things to keep in mind while making those changes that not all node in aem normally requires sling:resourceType so to get the list of nodes who are problematics you need to write some code may be node traversal to check with node path for all component normally last node name in the node path matches to the component name.
Few Examples:
/content/company/language/en/home/jcr:content/root/responsivegrid/text ---I if this node doesn't have any sling:resourceType you need to delete this one as it will be referencing to text component
Hope that helps
