Receiving java.lang.NullPointerException when trying to configure a plugin

Question

I'm trying to configure a SAML 2.0 plugin that has no support or documentation. In my dev instance of Jira, the plugin worked. It also worked in dev and prod instances of Confluence. When trying to configure the same plugin in my prod instance of Jira, I get the below error.

I can't find any reference to the plugin in any of the Jira logs or Windows Event Viewer. The log referral number doesn't come up either. Any pointers on where I can see what's going wrong so I can try to fix it?

Technical details

Log's referral number: 3c1060dc-290d-4fbb-8d56-e4ad9e01d8e6

Cause

Referer URL: https://jira.domain.com/plugins/servlet/upm

java.lang.NullPointerException

I can't post the full message due to character limitations, but it goes on for 260 lines. I am happy to post this in chunks.

Unfortunately per the vendor, they offer no support for this plugin. The best I can figure out based on the plugin code, the crash happens when I try to configure it because there's no configuration info for it to reference.

Sorry, I just wanted to make sure whether it can be because of any general subjects, but it is not.

NullPointerException is hidden in plugin code, so that you should raise a ticket to the vendor.

I had to post the trace here, as the forum software won't allow me to post it: https://pastebin.com/yAnqBPk3
