How to use CloudFunctions in a Xamarin project

Question

Is there a tutorial on how to properly call a cloud function using Xamarin.Firebase.iOS.CloudFunctions? Or how to setup a regular http request for it, without the library?

I set up my function like this:

exports.IsAppleSubscriptionActive = functions.https.onCall(async (data, context) => {});'''

and deployed it like this:

firebase deploy --only functions

and got and url like this:

https://[region]-[project-id].cloudfunctions.net/IsAppleSubscriptionActive

On the client I installed the nuget and I try calling:

var result = await CloudFunctions.DefaultInstance.HttpsCallable("IsAppleSubscriptionActive").CallAsync(payloadToSend);

where payloadToSend is a NSDictionary. I get

Foundation.NSErrorException: Error Domain=com.firebase.functions Code=13 "INTERNAL" UserInfo={NSLocalizedDescription=INTERNAL}

What am I missing? I feel like the native tutorials aren't helping either.

When using a regular http request I get a 500 status, in the logs I see something related to permissions accessing the secret manager (I use it for some api keys).

好的，所以代码没有任何问题，我只是没有向适当的用户授予适当的权限（我在我的云功能中使用了 Secret Manager）
