"TypeError: Failed to fetch" from failed attempt to connect to remote lake

[philrz]

Repro is with Zui commit 9d91dd3.

The attached video shows the same verification as in #1105 (comment), but in Dev mode which prominently displays unhandled errors as opposed to in production builds where they quietly go into the DevTools console. As this shows, when I attempt to connect to remote lake and it's accessible, an Unhandled Runtime Error "TypeError: Failed to fetch" is surfaced.
