Tried some different thing in include,exclude. Saw advise for add empty ts file and create but nothing change. Restart IDE(IntelliJ idea).

This error happens when there are no .ts files inside the project. This is happening because /src folder is not being copied to /app because the * only copies files inside a directory and not subdirectories. Change COPY ./backend/* /app to COPY ./backend /app.
