It's difficult to say for sure what is causing this error.  We in support have seen lots of similar error messages before on Jira Software boards.  That is where this error tends to show up.  Please check out the KB JIRA Software: "Exception: Uncaught TypeError: Cannot read property 'fields' (or 'html') of undefined".

In this case, I think we should try to focus on the 'getNamedItem' element in your error message.  There is likely a 3rd party plugin you have to Jira that is referencing that element in such a way to cause this error.  I would suggest trying to test out disabling user plugins in Jira to see if that can make this go away.  At least then you can learn more about what plugin is causing this.

If there are no plugins, please let me know what version of Jira this is and any other environmental settings that might exist so we can try to reproduce this.
