我尝试以编程方式触发事件（firebase 应用内消息），但 firebase 不显示任何消息。
在日志中我看到它：
2019-07-30 16:47:07.514 1890-1918/ru.ed.com.test.debug W/FIAM.Headless: Recoverable exception while reading cache: /data/user/0/ru.ed.com.test.debug/files/fiam_eligible_campaigns_cache_file (No such file or directory)

2019-07-30 16:47:07.541 1890-1918/ru.ed.com.test.debug W/ProviderInstaller: Failed to load providerinstaller module: No acceptable module found. Local version is 0 and remote version is 0.
2019-07-30 16:47:07.542 1890-1918/ru.ed.com.test.debug W/FIAM.Headless: Service fetch error: value
我是这样触发的：
FirebaseInAppMessaging.getInstance().triggerEvent("Draft campaign")
有人能帮我吗？什么问题？
