node.js - Firebase 消息传递 send() 错误与 UnhandledPromiseRejectionWarning

Question

我的以下代码有时似乎会出错，但我不确定为什么我无法捕获错误并收到 UnhandledPromiseRejectionWarning。

(node:18) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

            if (!_.has(persona_2.profile, 'push_token')) {
                return;
            }

            const { rowCount: badge } = await Chat.knex().raw(newChatCountSql, {
                personaId: context.user.profile.persona[0].id,
            });

            admin.messaging().send({
                token: persona_2.profile.push_token,
                notification: {
                    title: 'my title',
                    body: 'hello world',

                },
                // topic: chatId,
            })
                .catch(err => {
                    if (['messaging/invalid-registration-token', 'messaging/registration-token-not-registered'].includes(err.code)) {
                        // push token is no longer valid
                    } else {
                        log.error(err);
                    }
                });

错误是需要主题、 token 或条件之一。

因此有时persona_2.profile.push_token可能为空。

您能否检查一下 persona_2.profile 是否有 push_token key ，并且 persona_2.profile.push_token 不为空。

            if (!_.has(persona_2.profile, 'push_token') || !persona_2.profile.push_token) {
                return;
            }
