Hello Bhupesh,
This error usually occurs when you are stepping through a process and then change the stage using the "set next stage" function. This then disrupts the usual path of the process if it is already on a subsheet and it does not follow that it has been called as a page.
To amend this you can either set up the process so that it can run autonomously and not have to change the stages, or when the error appears set the next stage as the start of the page you would like to run.
Hope this helps
