Describe the bug

I am integrating Ory SDK in .NET Maui app. I started with registration flow. I tried multiple times to register with the following password:

Test@123

But each time I got null from the result. The registration code is:

new Ory.Client.Model.ClientUpdateRegistrationFlowBody
        (
            new ClientUpdateRegistrationFlowWithPasswordMethod
        (
            method: "password",
            password: registrationPassword,
                 traits: registrationTraits
        )
        );

        try
        {
            result = _frontendApi.UpdateRegistrationFlow(flowId, clientUpdateRegistrationFlowBody);
        }
        catch (ApiException e)
        {
            Debug.Print("Exception when calling FrontendApi.UpdateRegistrationFlow: " + e.Message);
            Debug.Print("Status Code: " + e.ErrorCode);
            Debug.Print(e.StackTrace);
        }

When I looked in the Logs & Events section of the Activity Tab in my Ory Network Project it says that the registration was failed. The json from the log:

{"name":"RegistrationFailed","timestamp":"2025-02-07T15:07:47Z","attributes":[{"key":"GeoLocationRegion","value":"WB"},{"key":"SelfServiceFlowType","value":"api"},{"key":"SelfServiceMethodUsed","value":""},{"key":"Reason","value":"the password does not fulfill the password policy because: The password has been found in data breaches and must no longer be used."},{"key":"FlowID","value":"2903936e-aafc-46fd-a609-ebf375c5ef55"},{"key":"ProjectEnvironment","value":"dev"},{"key":"GeoLocationCity","value":"Asansol"},{"key":"GeoLocationCountry","value":"IN"}]}
The sdk should get the error message when any flow fails in order to properly inform the app users.

Reproducing the bug

1. Run the following repro project
2. Try to register with any email and with password (Test@123)
3. Put the breakpoint in the result of the UpdateRegistrationFlow(flowId, clientUpdateRegistrationFlowBody) method.

Hello @HobDev

The error "the password does not fulfill the password policy because: The password has been found in data breaches and must no longer be used."

Please use a secure password instead of Test@123

Hello @vinckr

I used a secure password and successfully registered myself. But the api should return correct error message and error code so that the developer can inform the user about the mistake they are doing and/or take appropriate next steps in the app based on the error code.
