Using the full path including the prefix.

Routes inside a blueprint should be relative to the blueprint's URL prefix, so no leading slash is used.

Using blueprint name with slash.

The blueprint name is 'admin' and the URL prefix must start with a slash '/admin'.

💡 Hint

Common Mistakes

Using route with the full prefix path.

Incorrect URL prefix format.

The blueprint is named 'admin'. The route inside the blueprint is relative and uses '/'. The URL prefix is '/admin'.
