Page edit mode not working
Hi,
I'm not able to select page edit mode and when I click on "Edit" mode, it displays nothing. No drop-down is appearing to select and change page mode to Design or Targeting.
This issue seems to arise only in the higher environment like Staging, not on local. When I deploy code on local, I'm perfectly able to edit page or change mode.

I also tried changing the "Apache Sling Main Servlet" configuration i.e. changing the value "Number of Calls per Request" to higher values like 3000 or 5000 but still it's working.
In the browser console, I'm getting the following error:

Any suggestions on how to resolve this issue?
Best Regards,
Himanshu
