.NET SDK - ListRelations throws exception when relation is not found

[antonio-dfg]

Hello team 👋

We are implementing the ListRelations method (using the .NET SDK) and noticed that when passing a relation that does not exists, ListRelations is returning the following exception (relation not found), is this expected?

OpenFga.Sdk.Exceptions.FgaApiValidationError: relation 'agreement#can_do_something' not found

I would expect the following:

• When passing 2 relations that exists (can_do_A, can_do_B) and 1 relation that does not exist (can_do_something) in the authorization model:
  • Evaluate relations that exists (can_do_A, can_do_B) and return them (if user has relations)
  • Ignore relation that does not exist (can_do_something)

Another question is, there is a way to List the relations a user has on an object without passing the relations?
Asking because when using CLI this is possible by doing the following: fga query list-relations user:anne document:readme

Let me know your thoughts... 💭

Thanks and keep up the good work!
