data param in transformRequest is undefined

[JuoCode]

I want add API endpoint in transformRequest, but data param is undefined 😂

const API = axios.create({
  transformRequest: [(data, headers) => {
    console.dir(data);
    console.dir(headers);
    return data;
  }]
});

I use master

@JuoCode Can you share the code that sends the request?

[JuoCode]

export function fetchProjects () {
  return dispatch => {
    return API.get('http://example.com/projects')
      .then(response => {
        dispatch({ type: PROJECTS_RECEIVED, payload: response.data });
      });
  };
}

transformRequest allows changing the request body (data) and headers. Your code makes a GET request that has no body. That's why data is undefined.

If can try to use interceptors to change other request properties.

API.interceptors.request.use(
  config => {
    // request config can be changed here
    return config;
  }, 
  error => Promise.reject(error)
);
