Post Image to rest Api using form data (Ionic 3)

Hi, why i’m getting error 400 (Image not found) when post to rest api using formdata?

when i dump the server, it success but the preview are empty

Since you don’t show any code at all no one has any idea.

But, I did write a blog post on how to do this that would probably cover any issue you might have: http://roblouie.com/article/574/learn-ionic-cordova-file-upload/
