No URL was given.

Error message

No URL was given.

What it means

Thrown by NavigateUrl(string) when the resolved url is null or empty after IsNullOrEmpty check. The command requires a non-empty target before it can process template tokens (e.g. {DocsRootUrl}) and launch the browser, so an empty value is rejected up front.

Solutions

1. Check !url.IsNullOrEmpty() before calling NavigateUrl and skip if empty.
2. Validate Link objects have a non-empty Url before they reach the command.
3. Clean imported data to remove or default empty-URL link entries.

Example fix

// before
Commands.NavigateUrl(link.Url);

// after
if (!link.Url.IsNullOrEmpty())
{
    Commands.NavigateUrl(link.Url);
}

if (!url.IsNullOrEmpty())
{
    Commands.NavigateUrl(url);
}

try { Commands.NavigateUrl(url); }
catch (Exception e) when (e.Message.Contains("No URL was given"))
{ logger.Warn("Empty URL ignored."); }

When it happens

Trigger: Calling NavigateUrl with an empty string, null, or a value that resolves to empty (e.g. a Link.Url that was empty forwarded from the dispatcher).

Common situations: A game/​link has a blank Url field; a command binding passes an unbound/​empty property; string interpolation produced empty; a data import created link entries with no URL.
