谷歌云创建功能失败，docker_layer_cache上的缓存未命中

Question

我正在尝试创建我的第一个云函数，指向我的Github repo上镜像在谷歌云存储库上的一个分支。然而，该功能无法部署，并产生以下错误：

部署失败：

Build failed: {"cacheStats": [{"status": "MISS", "hash": "c6a7ea692f4ddc9f7088c33d4c6e337420dcdc1452daa09efb5054117e10be57", "type": "docker_layer_cache", "level": "global"}, {"status": "MISS", "hash": "c6a7ea692f4ddc9f7088c33d4c6e337420dcdc1452daa09efb5054117e10be57", "type": "docker_layer_cache", "level": "project"}]}
