Error handling ( e.g. network errors, bad params)

[nikamani]

Is your feature request related to a problem? Please describe. Currently if user types in a route that has bad params ( negative values, letters) frontend doesn't handle them at all. Or if backend returns 404 or something else goes bad there is currently no way of displaying errors or that something went wrong to user

Describe the solution you'd like Move network requests to a single location and have it handle issues correctly there ( fetch doesn't catch errors because promise just goes through try catch)

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Additional context Add any other context or screenshots about the feature request here.
