Shouldn't imageURL(forMode: , size: ) be available even in a limited login?

Goals

I want to get a large profile image using imageURL(forMode: , size: ) at loginTracking is .limited (using limited login)

Expected results

I want to get a large profile image using imageURL(forMode: , size: ), even when loginTracking is .limited.

I followed the documentation and implemented limited login. but imageURL(forMode: , size: ) returns the following error and does not provide valid image url even though loginTracking is .limited

{
   "error": {
      "message": "Invalid OAuth access token - Cannot parse access token",
      "type": "OAuthException",
      "code": 190,
      "fbtrace_id": "-"
   }
}

Looking at Profile+ImageURL's implementation, I see that it uses an "access token", but when login tracking is .limited, the method cannot be used because the access token is nil. Therefore, I cannot get a large profile image on limited login.

1. is this intended behavior?
2. is this limitation because profile images should not be used on limited login?
3. should I just use the imageURL to get the profile image for limited login?
   • The documentation used a property called Profile.current?.linkURL, but that property returns null even if there is actually a registered profile when limited login

If this is an error, I was wondering if it could be fixed soon.
Or if not, I'd like to know if there is a completely different approach.
