problem with custom skins in latest builds

[claudiobosticco]

Hello, I wanted to ask what might have changed in version 13.1 after the 20250329 build (the last working one) in the March 31 and April 1 builds. Basically, my custom skins no longer load the load_skin.js file.

The file is located at a path like:
./isomorphic/skins/1.1.9-13.1-p20250329/mySkin/load_skin.js?isc_version=13.1-p20250331.js

I load them using the skinDir attribute of the loadISC tag. The generated path in the script tag is correct, but in the browser, the file appears empty (while in the deployment, I can see that it is not empty).

Regular skins are loading normally.

now I've verified that if I deploy the custom skins directly under isomorphic/skins without the "versioning" subfolder, then everything works. But why the above path stopped working after 20250329 build?

I just realized that I'm using the FileDownload servlet with this mapping:

<servlet-mapping>
        <servlet-name>FileDownload</servlet-name>
        <url-pattern>/isomorphic/skins/*</url-pattern>
    </servlet-mapping>

so something must've changed there.

hi Claudio, thanks for the report.

We're not immediately seeing an issue delivering load_skin content for custom skins, even with the skin-dir being inside a sub-dir of skins/, which is indeed the most likely cause of an issue here - we're still investigating and will get back to you.

Can you confirm, is your custom skin from the Skin Editor? Did you "Export as a base skin" and, if not, what is the baseSkin?

Hello, yes it's from the skin editor, *not* exported as a base skin, the base skin is Shiva.
