SWORD v1 authorization on DSpace 9.2

[Joshua Kim]

Hello,

I am working on DSpace 9.2 on our sandbox. I enabled the SWORD server. I am an admin. I typed my login id and password correctly on  "https://#####.udel.edu/server/sword/servicedocument", but it has an error as below: 

=============

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Cannot invoke "jakarta.servlet.http.HttpServletRequest.getAttribute(String)" because "request" is null

===================

I checked dspace.log file and it says, "ERROR unknown unknown org.springframework.boot.web.servlet.support.ErrorPageFilter @ Forwarding to error page from request [/                                                                 sword/servicedocument] due to exception [Cannot invoke "jakarta.servlet.http.HttpServletRequest.getAttribute(String)" because "request" is null]

java.lang.NullPointerException: Cannot invoke "jakarta.servlet.http.HttpServletRequest.getAttribute(String)" because "request" is null"

Can anyone help me to figure out how to fix this issue?
