--------------------------------------
Hi I tried a small upload example on both development and production on 3.0.3
and 3.0.4-SNAPSHOT and not getting this error (tried both chrome and firefox)
!image-2026-01-21-07-44-16-725.png|width=755,height=248!
Can you provide an example where this error occurs with details on the browser
and platform?
