  • It might be a silly question, but are your sure your 'link api' is a well formed url ? Commented Apr 5, 2018 at 23:21

From what I can see, it's not an error from the http client directly, but from your server.

In a similar issue, the problem was coming from CORS and the fact that the Access-Control-Allow-Origin header was not correctly added in case the server response did not have a 20X or 30X status.

Did you check your server and log the call ?

Hope that helps

In the backend code, If you are using Spring boot add an annotation @Crossorigin right above the CRUD API call method.
