API calls error handling

All methods on NablaClient and NablaMessagingClient can return an error in their Result. This error will always be of type NablaError.

There are 2 types of exceptions you might want to handle specifically:

• NablaError.Network: for a network related error. You probably want to provide the user with a retry mechanism when this error happens
• NablaError.Authentication: when a call to NablaClient.authenticate is missing before calling an authenticated API or when the SessionTokenProvider failed to get fresh tokens

See all cases in the NablaError enum

Handling by UI components

If any error occurs, the Nabla UI component will handle it in one of the following ways.

• If error is global, e.g. we failed to fetch the list of conversation. Component will then show a text message with a retry button.
• If error is not global, e.g. we failed to load a second page of messages. Component will then show an alert explaining what failed.

In all cases, the error will also be logged.
