How to resolve error : Left side ($menuCurrentPage) of '==' operation has null value. If a reference, it may not be in the context. Operation not possible.

Hi,

 

The problem I am facing is that occasionally Resourcenotfound/unable to
parse file  error comes on the velocity pages which go on page refresh.

 

 

The following error is shown in the server logs before the logging of
resourcenotfound exception:

Left side ($menuCurrentPage) of '==' operation has null value. If a
reference, it may not be in the context. Operation not possible.

 

Is something related to the velocity engine here?

The problem is occurring right now only on staging site of my website, and
thankfully is not on Live. But it is happening a lot of times on staging and
is becoming troublesome

 

Thanks,

Rupali
