Originally created by @sgreadly on GitHub (May 6, 2025).

Issue very similar to #1179 when I googled.

Raspberry Pi 5 arm64

Server: Linux x 6.12.25+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.25-1+rpt1 (2025-04-30) aarch64 GNU/Linux

On Docker-ce

Client: Firefox 138 on MacOS.

I just did a clean install from the instructions here: https://hub.docker.com/r/linuxserver/heimdall/

It installed version 2.6.3.

Steps (bold line explained later below):

Click on "Add an application" in main page
In Preview page, click Application Type and choose one. My choice was XWiki
Then, click on "Website" just under that, and add a website (http://...) and click Go
It asks to select an icon, gives me 3 choices. I select any of them (all have same outcome)
Click on Save on the bottom.

Result:

It gives an error saying "Icon must be an image"
It then refreshes that same page, and all images are broken (see attached).

Unable to proceed with creating an application.

img src for the top broken image looks strange.

"src="http://myhost.lan/storage/http://mywiki.lan/resources/icons/xwiki/favicon16.png?cache-version=1741704314000""

Same with bottom one next to "Upload an icon"

Note:

The issue that breaks this is the one in bold above.

If I click on "Website", and add the URL there and it populates the rest of the preview page, then it breaks when I click Save. However
If I don't click on Website, and just enter the URL myself in the URL box mid-page, click on Save, that works and the Application is created.

Can close this off. I went with an alternative dashboard.
