System.InvalidCastException: Unable to cast object of type 'AsyncStateMachineBox`1[API.Entities.AppUser,API.Repository.UserRepository+<GetMembers>d__10]' to type 'System.IConvertible'. at System.Convert.ToInt32(Object value)

Question

Hi Again so this i a method where i get user id and there are two approaches to it one is that i use the get user by id(GetMembers()) method from the repository and use it

and its implementation

and when i call this method in the controller the following error occurs

the error isnt much so i use the convert.toint32 method to convert it into an integer
if i do that apprently the error goes away and when i call the controller in postman i get
System.InvalidCastException: Unable to cast object of type 'AsyncStateMachineBox`1[API.Entities.AppUser,API.Repository.UserRepository+<GetMembers>d__10]' to type 'System.IConvertible'.
at System.Convert.ToInt32(Object value)

Hi @Asjad Butt ,

From the above screenshot, we can know that the GetMembers method will return a Task<AppUser>, instead of an int value.

But from the above code and the error message, we can know that the GetUserWithLikes method required an Int type parameter. So, it will meet this issue.

To solve it, you can modify the code as below:

var sourceUserId = userRepository.GetMemebers(UserId)?.Result?.SourceUserId. //Assume "SourceUserId" is your property name, you can change it to yours.
