I am getting 500 Internal Server Error when I click on Manage Apps, however other functionalities are working fine.

Any quick help would be greatly appreciated.

What do you get in your splunkd log?

I don't see any specific error.

I see this error in the web access log.

And I don't see any error in the splunkd.log around the same time.

I am seeing this same error after upgrading to 8.0.2. It's only on 1 of my SH's, the others are functioning fine.

I am also seeing this issue when I click on "Update" to update one of the Apps in the Apps list.

The error page loads after about 4-5 seconds.

Ran into this issue - label was missing in one of the dashboard XML files.

If you're seeing this error message at the bottom of the stack trace - means this is a likely fix.
File "/opt/splunk/lib/python3.7/site-packages/splunk/appserver/mrsparkle/controllers/view.py", line 806, in buildViewTemplate
viewList.sort(key=lambda x: x['label'])
TypeError: '<' not supported between instances of 'NoneType' and 'str'

Quick workaround is to identify the dashboard XML without a label and update it.
https://docs.splunk.com/Documentation/Splunk/8.0.2/Viz/PanelreferenceforSimplifiedXML#Overview

<dashboard>
  <label>test_db</label>

Borrowed this from Engineering.

Here is a regex to find the labels causing the issue, run inside the splunk or diag folder
linux:
find . -name ".xml" | xargs grep -Pzo "(board.|orm.*)>\s+<\/label>"

I had the exact same problem.
I tried but it did not solve the problem.

find . -name ".xml" | xargs grep -Pzo "(board.|orm.)>\s+<\/label>"

I modified it as above but couldn't find a file.

In my case,
Label values were missing in some old dashboard xml files in other app.
(ex. )

After setting the label value, the dashboard such as manager was successfully loaded.
(ex. 111)

I'm experiencing this too after an upgrade to 8. Did you end up finding a resolution?

May be it is not problem of Splunk enterprise version. I think...

In my case,
The problem occurred when some dashboard had a label tag but no tag content.
When I added the string in label, the 500 error disappeared.

jcossin — Wed, 22 Apr 2020 18:31:36 GMT

Eventually found the culprit dashboard without a label tag applied and that resolved the issues.

The simple answer to this is you have a dashboard without a title. As soon as I fixed that, all the problems with 500 errors went away.
