@RequestMapping(value="edit/{postId}", method = RequestMethod.GET)
public String displayEditForm(Model model, @PathVariable int postId, Error error){

}

@RequestMapping(value="edit/{post_id}", method = RequestMethod.POST)

    thePost.setName(name);
    thePost.setLocation(location);
    thePost.setDescription(description);
    artifactRepository.save(thePost);
    return "index";
}

Error:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

    Artifact thePost = artifactRepository.findById(post_id).get();
