• Steps to reproduce the issue: Have a matching controller for an appservice and set the RemoteService(IsEnabled = false) attribute on the appservice

After upgradeing to ABP 4.4 a crud page returns the exception above

For this crud page there is a controller and an appservice. The appservice is hidden with the [RemoteService(IsEnabled = false)] attribute, which causes that the appservice is not visible for the outside world, the connection is made through the controller. However, in ABP 4.4 controllers are not found anymore on the host side (see the attached swagger screenshots of the host voor v4.3 and v4.4). This causes the exception.

We have several instances where we require a seperate controller and did not want both controller and appservice to be visible at the same time on the host. Following is some stripped code from v4.3 for the appservice and the controller. Is this method (using the remoteservice attribute) still supported? Why are controllers not visible anymore on the host side?

AppService:

[RemoteService(IsEnabled = false)]
public class QuestionPreCheckAppService : ApplicationService, IQuestionPreCheckAppService
{
	public virtual async Task<PagedResultDto<QuestionPreCheckDto>> GetListAsync(GetQuestionsPreCheckInput input)
	{
    ...
	}
}

Controller:

[RemoteService]
[Area("fs")]
[ControllerName("QuestionPreCheck")]
[Route("api/fs/questionPreCheck")]
public class QuestionPreCheckController : AbpController, IQuestionPreCheckAppService
{
	private readonly IQuestionPreCheckAppService _questionAppService;

	public QuestionPreCheckController(IQuestionPreCheckAppService questionAppService)
	{
		_questionAppService = questionAppService;
	}

	[HttpGet]
	[Route("GetList")]
	public virtual Task<PagedResultDto<QuestionPreCheckDto>> GetListAsync(GetQuestionsPreCheckInput input)
	{
		return _questionAppService.GetListAsync(input);
	}
}
