Custom App icons not showing

[tosplukornottos]

Hi,
I am running an on-prem installation of Splunk enterprise 7.3.0.
On this instance I've built an app and would now like to add icons to it. I've followed various guides where I was told to create a folder called static in the home directory of the app (called my_app below)and place my icons in there.
I did so, but I still couldn't get it to work. So eventually I removed my static folder from the my_app directory and copied over the content from search. The UI is still not updating. So I spun up a new docker, Splunk enterprise version 7.3.1.1 and imported the app from the other server with an SPL file. Still not updating.
On the new instance, I also created another app and tried to copy the icons from a third app to that one, without any luck.
I've made sure that the Splunk user is owning the files as well as the directory and tried to reach the data directly by browsing to this path on my Splunk server:

/en-US/splunkd/__raw/servicesNS/admin/my_app/static/appIcon.png

Any ideas on what might be the issue or how I can troubleshoot it?

I know this is an old post - but I also had this issue because the app creation in Splunk on-prem 9.2.1 puts the icon in the wrong place.  I opened up the browser inspector, turned off the cache, and watched for the png requests. From there I saw it was trying to get appname/static/appIconAlt_2x.png. I made the png at that location and I can see the preview now.

Happy Splunking!

It seems that a restart solved it. Everything was in place, but splunk needed restarting so I suppose I'll make sure that happens when installing the app in the future.

You need to create the folder/directory static in your app.

etc/app/your_app/static

Then I copied my png file into this directory and renamed it appIcon.png.

This is the default name the app uses when you create one

I would restart Splunk, sometimes you can get away with issuing a debug/refresh when updating certain content in your app
