条带创建用户firebase云功能

Question

我正在尝试在为firebase创建用户时创建一个条带用户，我一直收到此错误（下面显示错误）。该功能的代码也显示如下。如果我需要发布数据库结构，我将这样做，我目前没有条带客户的任何结构（这可能是问题发生的地方）。如果有人可以提供帮助我会非常感激。

错误：

Error: Reference.child failed: First argument was an invalid path = "/stripe_customers/${data.uid}/customer_id". Paths must be non-empty strings and can't contain ".", "#", "$", "[", or "]"

数据库结构：

Answer 1

在你的代码中你有这个：

ref('/stripe_customers/${event.params.userId}/customer_id')

此${event.params.userId}应该为您提供通配符的值，但由于您使用的是'，因此它也包含路径中的$。所以你需要改变它：

ref(`/stripe_customers/${event.params.userId}/customer_id`)

将'更改为“
