Invalid application ID with Facebook iOS application

Question

Here is the error when I try to login from my app.

MyApp[47747:907] Failed to log in Error Domain=com.facebook.sdk Code=2 
"The operation couldn’t be completed. (com.facebook.sdk error 2.)" 
UserInfo=0x1c5d3c50 {com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:SystemLoginCancelled, com.facebook.sdk:ErrorInnerErrorKey=Error Domain=com.apple.accounts Code=7 
"The Facebook server could not fulfill this access request: Invalid application [My_App_Id]"

On another iPhone the authorization works without problems. I checked that on both devices, My App is enabled for Facebook native auth.

Any ideas?

Ok, my mistake. I was trying with my friend's Facebook account and he was not identified as a developer on Facebook.

Once I disabled the Sandbox mode for my app, login worked without problems.
