I don't know how to solve this error. The error stops me more than two hours. I have to ask someone help me.

Answer 1

Your action below does not contain a type property which is required

export function loadArticles() {   return {     types:[LOAD_ARTICLES, LOAD_ARTICLES_SUCCESS, LOAD_ARTICLES_ERROR],     url:'./api/articles.json',   }; } 

You should modify the above code so that your action creator returns a type

export function loadArticles() {   return {     type: LOAD_ARTICLES,     url:'./api/articles.json',   }; }
