What did you do?

I have the following tokenProvider in my app:

private lazy var tokenProvider: TokenProvider = { [weak self] completion in
        _ = self?.authRepository.chatToken()
            .observeOn(MainScheduler.instance)
            .subscribe(
                onSuccess: { response in
                    if let chatToken = response.chatToken {
                        completion(.success(Token(stringLiteral: chatToken)))
                        do {
                            let decoder = JWTDecoder()
                            let jwtData = try decoder.decode(jwtToken: chatToken)
                            if let exp = jwtData["exp"] as? TimeInterval {
                                self?.tokenExpiryTime = exp
                                self?.tokenExpiryDate = Date(timeIntervalSince1970: exp)
                            }
                        } catch {
                            completion(.failure(AppErrors.generic))
                        }
                    } else {
                        completion(.failure(AppErrors.generic))
                    }
                },
                onError: { error in
                    completion(.failure(error))
                }
            )
    }

If the authRepository.chatToken() fails with, for example, a 401 error, the stream chat will start repeatedly calling the tokenProvider and failing.

What did you expect to happen?

The completion handler of the connectUser to be called with an error. Or a way to break out of the loop.

What happened instead?

An infinite loop.
