I have created a thymeleaf form and under that form(link as below) total 10 fragments are there. In the attached code you will found that two(photo-fragment and idproof fragment) fragments load have been disabled. When I am turning on those fragments I am getting 500 error in production system but it is working as expected in UAT and DEV. Please help.

Complete form: I am facing the issue, when I am uncommenting the commented lines. Photo and Idproof fragments are as below.

Photo fragment:

Id proof fragment:

I have tried to replicate that scenario in development system and UAT environment but there I am not getting 500 error. In production also it should work as UAT and development.
