[BUG] 401 Unauthorized for Thumbnails

[de-ich]

Describe the bug
When using the authorization feature of the AAS environment, trying to retrieve the thumbnail of an AAS always returns "401 Unauthorized".

To Reproduce
Steps to reproduce the behavior:

1. Clone the basyx-server-sdk repo
2. Run "docker compose up" in the "BasyxSecured" example folder (https://github.com/eclipse-basyx/basyx-java-server-sdk/tree/main/examples/BaSyxSecured)
3. Login to the UI using user "john.doe" (pw "johndoe") - a user with admin rights (read/write for everything)
4. Click on the "Demo AAS V3" - an AAS with a thumbnail defined
5. Notice that the thumbnail is not displayed and a 401 error is shown in the console/network tab of the browser

This behavior also happens with other AAS that include a thumbnail.

Expected behavior
The thumbnail is retrieved/displayed if the user has read rights for the AAS

BaSyx (please complete the following information):

• BaSyx v2.0
• BaSyx Java SDK
