fix: cloud map error state offline mode

[victorgaard]

Problem

If a given user has loaded the Komiser dashboard, visited the Inventory page, lost internet connection or closed the server, then went back to the dashboard, they will be served either with a default browser error screen (i.e.: there is no internet connection...) or with the Next.js cached HTML/JS version of the page, which shows the dashboard widgets with the error state.

In the case they receive the cached version, the cloud map error state would render like this:

We use an SVG to display the world map as a placeholder, so since there is no connection to load the file, it displays its alt text instead.

Solution

Remove the alt property, so in this specific scenario of no internet connection, they would just see a blank space where the map should be.

The error state (not in offline mode) can be observed from the Storybook:
