🐛 Bug Report: Bug acquiring users on server side

[joaquingrech]

👟 Reproduction steps

this method:

sdk-for-dotnet/src/Appwrite/Models/User.cs

Lines 102 to 120 in 5c20443

	public static User From(Dictionary<string, object> map) => new User(
	id: map["$id"].ToString(),
	createdAt: map["$createdAt"].ToString(),
	updatedAt: map["$updatedAt"].ToString(),
	name: map["name"].ToString(),
	password: map["password"]?.ToString(),
	hash: map["hash"]?.ToString(),
	hashOptions: map["hashOptions"]?.ToString(),
	registration: map["registration"].ToString(),
	status: (bool)map["status"],
	labels: ((JArray)map["labels"]).ToObject<List<object>>(),
	passwordUpdate: map["passwordUpdate"].ToString(),
	email: map["email"].ToString(),
	phone: map["phone"].ToString(),
	emailVerification: (bool)map["emailVerification"],
	phoneVerification: (bool)map["phoneVerification"],
	prefs: Preferences.From(map: ((JObject)map["prefs"]).ToObject<Dictionary<string, object>>()!),
	accessedAt: map["accessedAt"].ToString()
	);

the issue is that when you do this on the server from the JWT token:

var client = new Client()
        .SetEndpoint("https://cloud.appwrite.io/v1")    // Your API Endpoint
        .SetProject(projectid)                     // Your project ID
        .SetJWT(token);

var appWriteUser=(await (new Account(client)).Get());

The way it does this internally is that Get() makes an api call, retrieves a dictionary and then calls the User.From
since the dictionary does not retrieve the password, you get an exception with Key not found "password" and it crashes
meaning you can never retrieve a user on the server side, never
exact exception details details

"error":"System.Collections.Generic.KeyNotFoundException: The given key 'password' was not present in the dictionary.\r\n   at System.Collections.Generic.Dictionary2.get_Item(TKey key)\r\n   at Appwrite.Models.User.From(Dictionary2 map)\r\n   at Appwrite.Services.Account.<Get>g__Convert|1_0(Dictionary2 it)\r\n   at Appwrite.Client.Call[T](String method, String path, Dictionary2 headers, Dictionary2 parameters, Func2 convert)

👍 Expected behavior

it should create an user instance with the missing information (no password)

👎 Actual Behavior

exception as explained, and no user created

My quick fix was this on User.cs. Open to better solution. I only identified as potential "nulls" password, hash and hashOptions. I don't know whether all other fields are always populated for every user account.

private static object? getFromMap(Dictionary<string, object> map, string key)
{
object? val;
map.TryGetValue("password",out val);
return val;
}
public static User From(Dictionary<string, object> map) {
return new User(
id: map["$id"].ToString(),
createdAt: map["$createdAt"].ToString(),
updatedAt: map["$updatedAt"].ToString(),
name: map["name"].ToString(),
password: getFromMap(map,"password")?.ToString(),
hash: getFromMap(map,"hash")?.ToString(),
hashOptions: getFromMap(map,"hashOptions")?.ToString(),
registration: map["registration"].ToString(),
status: (bool)map["status"],
labels: ((JArray)map["labels"]).ToObject<List>(),
passwordUpdate: map["passwordUpdate"].ToString(),
email: map["email"].ToString(),
phone: map["phone"].ToString(),
emailVerification: (bool)map["emailVerification"],
phoneVerification: (bool)map["phoneVerification"],
prefs: Preferences.From(map: ((JObject)map["prefs"]).ToObject<Dictionary<string, object>>()!),
accessedAt: map["accessedAt"].ToString()
);
}

Thanks for your quick fix, but I think your getFromMap is not implemented as desired.
You implemented a hardcoded value "password" in TryGetValue. I guess instead it should be:

map.TryGetValue(key,out val);

A more compact version would be:

private static object? getFromMap(Dictionary<string, object> map, string key)
{
    return map.TryGetValue(key, out var val) ? val.toString() : null;
}

My suggestion would probably be to change it inline as follows:

public static User From(Dictionary<string, object> map)
{
  return new User(
    id: map["$id"].ToString(), 
    createdAt: map["$createdAt"].ToString(), 
    updatedAt: map["$updatedAt"].ToString(), 
    name: map["name"].ToString(), 
    password: map.TryGetValue("password", out var password) ? password.ToString() : null,
    hash: map.TryGetValue("hash", out var hash) ? hash.ToString() : null,
    hashOptions: map.TryGetValue("hashOptions", out var hashOptions) ? hashOptions.ToString() : null, 
    registration: map["registration"].ToString(), 
    status: (bool)map["status"], 
    labels: ((JArray)map["labels"]).ToObject<List<object>>(), 
    passwordUpdate: map["passwordUpdate"].ToString(), 
    email: map["email"].ToString(), 
    phone: map["phone"].ToString(), 
    emailVerification: (bool)map["emailVerification"], 
    phoneVerification: (bool)map["phoneVerification"], 
    prefs: Preferences.From(((JObject)map["prefs"]).ToObject<Dictionary<string, object>>()),
    accessedAt: map["accessedAt"].ToString());
}

So we would not need to add an extra function. And I would use named parameters when creating the User-object. Having positional arguments is confusing if the list is so long and not readable. ;)

yep, I hardcoded for testing "password" and forgot to remove it. Glad there is a fix already on the way.
