GetAndroidConfig using firebase management service C# .NET returning Google.GoogleApiException: Parameter validation failed for "parent"

After creating a web app config in firebase using the c# library, I wanted to get the configuration file, but I am getting error :- Google.GoogleApiException: Parameter validation failed for "parent" : The value did not match the regular expression ^projects/[^/]+$ ….. as shown below , how do I fix this issue?

     public static WebAppConfig GetWebAppConfig()
   {
        var listWeb = _firebaseManagementService.Projects.WebApps.List("projects/" + CloudManager.ProjectId + "/webApps").Execute();
        return _firebaseManagementService.Projects.WebApps.GetConfig("projects/-/webApps/" + listWeb.Apps[0].AppId + "/config").Execute();
   }

Edited -> The error that displays in my terminal is as shown below

Unhandled exception. The service firebase has thrown an exception.
No HttpStatusCode was specified.
No error details were specified.

    The problem was on this line,

    var listWeb = _firebaseManagementService.Projects.WebApps.List("projects/" + CloudManager.ProjectId + "/webApps").Execute();

    And removing /webApps resolved the issue

    var listWeb = _firebaseManagementService.Projects.WebApps.List("projects/" + CloudManager.ProjectId).Execute();

    Your config path in the second call seems to be malformed.

    return _firebaseManagementService.Projects.WebApps.GetConfig("projects/-/webApps/" + listWeb.Apps[0].AppId + "/config").Execute();

    Let’s imagine that listWeb.Apps[0].AppId contains "foo-app-id".
    That would result in the path parameter for the GetConfig call to be set as "projects/-/webApps/foo-app-id/config". This doesn’t seem like a valid path for Google Cloud Platform (the dash after "projects/" is what’s off).

    I’d guess you want to use your CloudManager.ProjectId variable value in this path too:

    return _firebaseManagementService.Projects.WebApps.GetConfig("projects/" + CloudManager.ProjectId + "/webApps/" + listWeb.Apps[0].AppId + "/config").Execute();
