                401 -> Result.Error(NetworkError.AuthError.TOKEN_EXPIRED)
                else -> Result.Error(NetworkError.AuthError.UNKNOWN_ERROR) // This is what it catches
            }

            Result.Error(NetworkError.AuthError.UNAUTHORIZED)

This block returns the comment line. But if i move some lines form try block like

        val token = dataStore.getJwt()!!
        val user = api.getCurrentAuthUser(token)
        return try {
            Result.Success(user.toUser())
        } catch (e: SerializationException) {
            Result.Error(NetworkError.AuthError.TOKEN_EXPIRED)
        } catch (e: ClientRequestException) {
            when (e.response.status.value) {
                401 -> Result.Error(NetworkError.AuthError.TOKEN_EXPIRED)
                else -> Result.Error(NetworkError.AuthError.UNKNOWN_ERROR)
            }
        } catch (e: NullPointerException) {
            Result.Error(NetworkError.AuthError.UNAUTHORIZED)
        }

I get
io.ktor.client.plugins.ClientRequestException: Client request(GET https://dummyjson.com/auth/me) invalid: 401 . Text: “{“name”:”TokenExpiredError”,”message”:”Token Expired!”,”expiredAt”:”2024-05-24T12:51:44.000Z”}.
This confirms the error must be ClientRequestException with error code 401.
