Hi,
Flow UI applications now is experimental and non-stable in Jmix.
From stacktrace, I can assume that the problem is in the wrong file path to “screen-designer” directory.
Сould you clarify if this problem also occurs on other projects or only on current project?

#5

Only in the Flow UI projects. The single module projects work fine. So I guess need to modify the file path or move the “screen-designer” directory to where it is expected? Thanks for your assistance!

#7

Hi,
You can try create a new project with the different name, probably it was happened because studio cannot correct parse path to “screen-designer” directory (from your stacktrace we can see “\jm_flow1.jmix” part of the path when missing ‘’ separator before “.jmix” directory).

Also, you can attach a project and we will create a ticket.
