Error message

Resources.Validation_ApiKeyRequired

What it means

The Gemini API key dialog in AccountSettingsViewModel validates input with ValidationException(Resources.Validation_ApiKeyRequired), thrown when the key is null or whitespace. The message text is the localized resource string named Validation_ApiKeyRequired, so the runtime message is the localized 'API key required' text rather than the literal resource name.

Solutions

1. Obtain a Gemini API key from Google AI Studio and paste it into the field before confirming.
2. Trim whitespace around the pasted key.
3. If the message shows the raw resource name, refresh/repair the localized Resources files so Validation_ApiKeyRequired resolves.

Example fix

// before
throw new ValidationException(Resources.Validation_ApiKeyRequired);
// after
throw new ValidationException(string.IsNullOrWhiteSpace(Resources.Validation_ApiKeyRequired)
    ? "API key is required" : Resources.Validation_ApiKeyRequired);

if (string.IsNullOrWhiteSpace(geminiKey)) {
    // get a key from Google AI Studio before opening the dialog
    return;
}

bool HasGeminiKey(string? s) => !string.IsNullOrWhiteSpace(s);

try { await ShowGeminiKeyDialog(); }
catch (ValidationException ex) { ShowStatus(ex.Message); }

When it happens

Trigger: Submitting the 'Set Gemini API key' dialog (AccountSettingsViewModel.cs:652) with an empty or whitespace-only key.

Common situations: User has not obtained a Google AI Studio API key; paste failed or pasted only spaces; masked password field hides emptiness; missing/older resource assembly yields an unexpected message text.
