I am using Firestore auto generated ID for my url path segment. It is separated by forward slash /.
For example, localhost:4200/follower/followerId/followed/followedId.
Both followerId and followedId are using Firestore auto generated id. My url path segment (using Angular) which separates url using forward slash such that localhost:4200/follower/:id/followed/:id
Therefore, does Firestore auto generated id contains forward slash?
It's not possible for a collection ID or document ID to contain a slash. It's not a valid character.
Please see the documentation for more details.
