Splunk Platform Upgrade Readiness App Read Error

[thscheidegger]

I'm trying to run the app version 2.0 on Splunk 7.3.3 on Windows Server 2016. Even as Admin I always get the error 'read'. In the instructions this is referred as a known issue if the permissions are insufficient. I had no problems on Linux, is there an issue with Splunk on Windows?

Thanks to the help of a colleague we found the solution:

| rest /services/apps/local
| table title eai:acl.perms.read

find the app(s) with no read permission and correct it

It seems to be because an app has no read permission set. I found it by searching the request (/services/apps/local?output_mode=json&count=0) and for an app without read. Then set read permission and it works

The same issue is happening on OS X as well. I was not able to test the solution on windows servers, but I simulate the issue in my local Splunk Enterprise running on OS X and it had fixed the issue. I am not able to find where the permission issues are on OS X, I re-apply the permissions on Mac, but it did not fix the issue.
What I did to get this correct working, I did a back from etc folder, remove Splunk Enterprise, reboot the server and Install Splunk Enterprise, Splunk Platform Upgrade Readiness App and it had worked.

The errors I get on the Windows installation are not very useful
