Swift Facebook Login sdk error with code 2 - swift

Question

I am getting an error while logging in with Facebook. And it was working about 3-4 months ago.
Now I am back at developing this app again and I changed the development target to iOS 13.0 from iOS 12.0 and add the SceneDelegate and other necessary things. Actually, I don't think this is the reason but good to mention.
Now I am getting this error:
FBSDKLog: Cannot login without a valid login configuration. Please
make sure the LoginConfiguration provided is non-nil Error
Domain=com.facebook.sdk.core Code=2 "(null)"
UserInfo={com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Cannot login
without a valid login configuration. Please make sure the
LoginConfiguration provided is non-nil}
while running this:
fbLoginManager.logIn(permissions: ["email, public_profile"], from: self) { (loginResult, error) in
if error != nil {
print(error!)
}
if let currentToken = AccessToken.current {
let credential = FacebookAuthProvider.credential(withAccessToken: currentToken.tokenString)
Auth.auth().signIn(with: credential) { (authResult, error) in
if let error = error {
let authError = error as NSError
print(authError)
} else {
DispatchQueue.main.async {
self.setupTabbar()
self.dismiss(animated: true, completion: nil)
}
}
}
}
}
I checked info.plist several times and apply the instructions from scratch but I am still getting this error.
I am using XCode 12.5 and Swift 5
Edit: When I remove the permissions it works but I actually need those permissions.

Solution
I changed permissions from ["email, public_profile"] to:
["email", "public_profile"]
so it looks like this:
fbLoginManager.logIn(permissions: ["email", "public_profile"], from: self) { (loginResult, error) in
if error != nil {
print(error!)
}
if let currentToken = AccessToken.current {
let credential = FacebookAuthProvider.credential(withAccessToken: currentToken.tokenString)
Auth.auth().signIn(with: credential) { (authResult, error) in
if let error = error as NSError? {
print(error)
} else {
DispatchQueue.main.async {
self.setupTabbar()
self.dismiss(animated: true, completion: nil)
}
}
}
}
}
