❔ RequestSizeLimit on Actions not Working!

I have an action that is uploading a large file. The file size is 189mb. For some reason I'm getting this error 413 Error: Request Entity Too Large. I even tried adding the RequestSizeLimit attribute on top of the action but it still has no effect. Here is the action

[RequestSizeLimit(int.MaxValue)]
    [HttpPost]
    [Authorize]
    [SwaggerOperation("An action for creating an episode.")]
    public async Task<IActionResult> CreateEpisodeAsync([FromForm] CreateEpisodeRequest request,
        CancellationToken cancellationToken = default)
    {
        var result = await _mutationService.CreateEpisodeAsync(request, cancellationToken);
        var response = result.ToApiResponse();

        if (result.IsSuccessful)
            response.StatusCode = HttpStatusCode.Created;
        else
            response.StatusCode = result.ErrorCode switch
            {
                ErrorCode.NotFound => HttpStatusCode.NotFound,
                ErrorCode.InternalServerError => HttpStatusCode.InternalServerError,
                _ => HttpStatusCode.BadRequest
            };

        return response.ToActionResult();
    }

[RequestSizeLimit(int.MaxValue)]
    [HttpPost]
    [Authorize]
    [SwaggerOperation("An action for creating an episode.")]
    public async Task<IActionResult> CreateEpisodeAsync([FromForm] CreateEpisodeRequest request,
        CancellationToken cancellationToken = default)
    {
        var result = await _mutationService.CreateEpisodeAsync(request, cancellationToken);
        var response = result.ToApiResponse();

        if (result.IsSuccessful)
            response.StatusCode = HttpStatusCode.Created;
        else
            response.StatusCode = result.ErrorCode switch
            {
                ErrorCode.NotFound => HttpStatusCode.NotFound,
                ErrorCode.InternalServerError => HttpStatusCode.InternalServerError,
                _ => HttpStatusCode.BadRequest
            };

        return response.ToActionResult();
    }

@Nathaniel TA Thanks mate, after a lot of testing. I realized it was using IIS in Debug and Kestrel in Production. I changed it to use Kestrel on both debug and production. For some reason, the attribute then started working. It sounds weird.

@SwaggerLife I think IIS has an internal limit that was rejecting it before it even reached your service. np

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
