I’m getting “java.lang.ClassNotFoundException: org.apache.commons.io.function.IOIterator”
You are probably using another library with an old version of commons.io, you need to upgrade it to 2.13.0 I think
You can check in your maven/gradle dependencies
Just for the record here’s a similar issue, fixed as mentioned by @faithful-emu Cannot upload in 24.2.0 (works fine in 24.1.12) · Issue #17872 · vaadin/flow · GitHub
Thank you very much! This was exactly the problem. Very good support!
