Gin middleware not receiving custom error

I'm throwing some error in my route handler:

func getQuestion(c *gin.Context) {
  err := errors.New("some error")
  c.JSON(http.StatusNotFound, gin.H{"msg": err.Error()})
}

And inside the middleware:

func errorMiddleware() gin.HandlerFunc {
  return func(c *gin.Context) {
    // Now, how to get that "some error"?

Ah, I have to put error in context:

c.Error(err)
