Bug: Error 500 (java.io.IOException) while uploading avatar to KNIME Hub

Hi KNIME team,

I am trying to update my avatar on the KNIME Hub, but I keep getting an "Error while uploading avatar" message. I have already tried using a 256x256 PNG and a very light 13.5kb JPG, but the error persists.

Looking at the browser's network tab, the server is returning a 500 status code. Here are the exact headers and IDs from the failed request so your backend team can trace the issue:

• Status Code: 500 Internal Server Error

• Knime-Exception-Class: java.io.IOException

• Error ID: error_a81b9c36-ab30-4b5d-bf77-b6ec9f87975d

• X-Request-Id: a19651b7-8cb5-4fae-a5e3-adb857e007ca

Could you please look into this? Thank you in advance!
