更新时控制台日志错误，Firebase 控制台

Question

我在我的 firebase 控制台中部署了 Typescript 中的这个函数：

import * as functions from 'firebase-functions'
import * as admin from 'firebase-admin'

admin.initializeApp()


export const onEditModeUpdate = 
functions.firestore.document("Settings/ShiftsEditMode").onUpdate(change => { 
    if (change.after) {
        const after = change.after.data();
        const payload = {
            data: {
                temp: String(after.temp),
                conditions: String(after.conditions)
        }
    }
    return admin.messaging().sendToTopic("Settings/ShiftsEditMode", payload)
}
else {
    return null;
}
})

部署是正确的，但是当我更改数据时，控制台日志中出现错误：

Error: Topic provided to sendToTopic() must be a string which matches the format "/topics/[a-zA-Z0-9-_.~%]+".
at FirebaseMessagingError.Error (native)

任何我做错的建议。

仔细阅读错误信息：

Error: Topic provided to sendToTopic() must be a string which matches the format "/topics/[a-zA-Z0-9-_.~%]+".

您提供的字符串 "Settings/ShiftsEditMode" 与要求的模式不匹配。该模式表示字符串应以“/topics/”开头。字符串的其余部分，即您的主题名称，只能包含字母、数字、下划线、点、波形符和百分比。您提供的字符串也不匹配该模式，因为它包含非法斜杠。
