Injecting currentPage using annotations does not return the correct page

https://github.com/adobe/aem-sample-we-retail-journal/issues/53

The same issue I was facing Breadcrumb was working fine in my local but UAT was not working I followed the above link and fixed the issue it worked in the UAT server. But once deploy to the Production server it is not working.

My code:

Page currentPage = request.getResourceResolver().adaptTo(PageManager.class)
.getContainingPage(request.getResource());

Instead of 

@ScriptVariable
private Page currentPage;

Before this fix: It was showing child pages of the root page. All pages were displayed irrespective of the hideInNavigation property.

 /content/page1/page2/page3/page4/page5

After Fix:

page3/page4/page5

It solved the problem, but it is working fine QA/UAT server but in production server not working.

In Production: Displaying all the pages

/content/page1/page2/page3/page4/page5

Please can help me with this issue?
