Unable to setup processor: Unable to get component of class 'interface org.apache.sling.rewriter.Transformer'

[RashidJorvee]

Today, I am facing an issue which is very annoying.

Issue: HTML page from content are not getting load properly and showing only a white page.

All bundles are active and I have restarted the AEM as well, but still, I am getting blank page only even for OOTB pages[http://localhost:4502/content/we-retail.html].

Then I looked in the error log and found the following error log. Could you please help me to understand this incident and what cause this issue and how I can fix this?

[GaneshM · Accepted solution]

Hi Rashid,

Looks like you configured the link Transformation Factory and transformerType is not matching with your Factory class.

Look for "TransformerFactory" class in your codebase and the "pipeline.type" should match with your transformerType configuration in UI codebase. Look for "TransformerType" and the value should match with "TransformerFactory" pipeline.type.

OR

Disable the Transformer by selecting false for "enabled"

Eg:

@Component(property = { "pipeline.type=linkType" }, service = { TransformerFactory.class })

public class LinkTransformerFactory implements TransformerFactory {

When I change the my transformer factory value to linkType to linkType1  I got the same error.

org.apache.sling.api.SlingException: Unable to setup processor: Unable to get component of class 'interface org.apache.sling.rewriter.Transformer' with type 'linkType'

Hope this helps!

Thanks!
