panic error when use wildcard route and not found

This is my code:

package main

import (
    "github.com/labstack/echo"
    mw "github.com/labstack/echo/middleware"
)

// Handler

func main() {
    e := echo.New()
    e.Use(mw.Logger())
    e.Use(mw.Recover())
    e.SetDebug(true)

```
e.Get("/:id", func(c *echo.Context) error {
    return c.String(200, ":id...")
})

e.Run(":1323")
```

}
