Context

When attempting to cast a vote on any proposal using a test wallet, the Blockfrost API returns an error due to exceeding the usage limit:

Error: BlockFrost [Status 402]: Usage is over limit

Response:

{
    "error": "Project Over Limit",
    "message": "Usage is over limit.",
    "status_code": 402
}

However, this error is not properly handled in the governance action voting process. Instead of displaying an error message, the application shows a blank screen.

Actual Behavior

• A blank screen appears when an error occurs on Cardano Network.
• The UI does not display any feedback or error message to inform the user about the issue.

Expected Behavior

• Instead of a blank screen, a modal popup should be displayed to inform the user about the API usage limit error.

@kneerose It looks like the exception isn't handled on the kuber service side. Might it be the case? As any execution of {wallet}.submitTx is properly handled by catch in govtool wallet service, or at least I can't find any place where we might have any exception leak.

Could you please provide more context, reproduction steps, or some vid displaying the error?

• The same error was handled correctly on govtool during dRep registration. The blank screen issue only occurs when casting a vote.
