403 error img does not show after publish

hi!

I’m having a weird problem with the images in my webflow project. I’m using zapier to get content (including images) from google docs inside webflow cms (it works fine in other project I did).

In the preview mode the images are shown normally but when I publish they disappear.
When I get inside the inspect I see that the img src link is different than the one in the preview mode. in the preview mode the img src has this opening::
https://lh3.googleusercontent.com/

but when after I publish the project the img src changes to this opening:
https://assets.website-files.com/
and for some reason this link doesn’t work and I get a bunch of 403 errors in the console.

btw, if I change the opening of the src link in the inspect the img is shown. So before I start writing scripts that change the link opening, does anyone have an idea why this weird thing is happening? thanks a lot!
