How to upload my image file with my token, Vue JS

I'm trying to upload my image so that it goes to my API, the thing is the validation needs to stay on the page, after they have logged in. It works with the upload through postman, by when i try to do it in the frontend of my Vue code it doesn't.

If someone knows how I can change this code to make it work, please let me know.
