Error: GET 404 (Not found) error for images, but the images are showing up fine

I am creating a MEAN app with images in one of my models. When the page loads, the images are rendering fine on the page but in my console I am getting this error about them: GET http://localhost:3000/%7B%7Bitem.photo_url%7D%7D 404 (Not Found) and in my terminal thats running npm and mongod: GET /%7B%7Bitem.photo_url%7D%7D 404 1.999 ms - 2083

I'm unsure what's causing this error, as on the front-end it seems to be fine. Any advice would be appreciated! Thank you!
