Dear @Gassim
I am very sorry to have posted and delayed my response this much. I am only realising this now. It was kind of surprising that the two programs on one instance behaved differently. Covid19 registry performed very will while HPV raised this error.
Two weeks back, I managed to solve this by deleteing server cache (the folder created by .war file).
Your input to this community is pretty much appreciated. Thank you very.
