Hello Tim,
thanks for your reply. The URL I mentioned before shows the Java stack

Hello,
if I read the code correctly, the NullPointerException seems to occur
while retrieving the handle of the parent DSpace object (i.e. the
collection that 123456789/77186 is supposed to be in) before generating
the Browse->This Collection links.
Perhaps there is some problem in the database - either with connecting
the collection to item, or with the handle of the parent collection.

Hi Gustavo,
A NullPointerException in Java is a generic error that could have
many different causes. So, we'd need more information about where
this error is occurring. If you need help finding the error stack
in your logs, please see this guide:
https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error
<https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error>
Please be sure to post the error stack to this mailing list, and
hopefully someone on this list will be able to more easily help you.

After upgrading to DSpace 6.2, we're receiving
java.lang.NUllPointerException when visualizing some items
(example:
https://repositorio.ufsc.br/xmlui/handle/123456789/77186
<https://repositorio.ufsc.br/xmlui/handle/123456789/77186>).
The problem occurs both in JSPUI and XMLUI.
We had some problems with items that didn't have the
"dc.date.issued" attribute set, but it is not this case.
Is someone experiencing similar issues?
