Show reasonable error messages in UI when request processing fails on server #23

Closed ledsoft closed 3 months ago

If request processing fails on server (e.g., we are unable to parse pattern), the frontend should display a reasonable error message informing the user what happened.

Moreover, the application should discard any old session data so that the UI does not show stale or incorrect values.
