将发布者存储在AnyCancellable设置中时的错误

Question

一些用户使用set使用anycancellable.store（in：） method中存储set。错误可能发生在10％的用户中，我无法真正复制它。

这是代码的简化版本：

    private var cancellables = Set<AnyCancellable>()
    private func doSomeWork() {
        doMoreWork() {
            DispatchQueue.main.async { [weak self] in
                guard let self = self else { return }

                service.valuesPublisher
                    .sink { [weak self] something in
                        self?.doSomeWork(something)
                    }
                    .store(in: &self.cancellables)
            }
        }

错误的日志如下：

我不知道为什么会发生任何提示？
