My issue is resolved Now.

Root Cause: Approval task had hyperlink pointing to original request form. In order to open infopath in browser we had concatinated "?OpenIn=Browser" at the end of URL.

During runtime due to some issue Persistent URL was getting generated for hyperlink instead of complete URL to request form. Persistent URL with text "?OpenIn=Browser" was giving mentioned error in this case.
