Facebook browser CORS issue

Question

Trying to figure out an issue that popped up in Sentry today.

I've never seen the 'Facebook' browser come up before, but here it is, all seem to be ios devices:

I don't really understand how there could be an origin issue here as the url listed has the same root domain. Has anyone run into this before?

Answer 1

This means someone is opening your url within the facebook app. Facebook app has its own browser shell to open the link within the app.

You will be able to replicate this issue if you open it from within the facebook app.
