Hi everyone,
I have been using my Dspace for the past one year. When I try to upload new
item recently, I could not move to the 2nd part of the submission page. The
following error message shown:
"Internal System Error"
The error which I identified from the dspace.log file is as follows:
2022-07-20 14:51:36,912 ERROR

Because of this, many uploading works are stuck in my library.
Please help me to sort out this issue.
Thank you.
