I'm reaching out to seek your assistance with resolving some WARN errors that have been appearing in error.log file

2. *WARN* GET /content/wknd/child1/child2/child3.html HTTP/1.1] com.day.cq.wcm.webservicesupport.impl.ConfigurationManagerImpl Cloud service /etc/cloudservices/generic-tracker/GA not found

3. *WARN* [WorkflowModelGenerationThread] com.adobe.granite.workflow.console.generate.WorkflowModelGeneratorImpl Errors detected in the the model at /libs/settings/workflow/models/ac-newsletter-workflow-simple.

1. Have you created this page child3 pro-grammatically ?  The jcr:primaryType of a page is cq:Page and not cq:page and hence the  error.
2. The second issue most likely looks like a missing cloudservice  configuration on the page. see if this  page or the root page of this content tree needs to be updated with this cloud service configuration in the page properties. 
3. For this one, you may have to inspect the participant step in your workflow model and see if the referenced participant is valid  and exists.
