Asp.net 7 core. Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Unexpected end of request content

Question

Sometimes, handling request in controller

[ApiController]
[Route("api")]
public class FrontWcController : ControllerBase

[HttpPost("change")]

        int actionNumber = requestData.ActionNumber;
        int operationNumber = requestData.OperationNumber;
        int checkBox = requestData.CheckBox;

        string actionHumanString = "Undefined";

        switch (actionNumber)
        {
            case 1:

                Console.WriteLine("Cant change status. Set to default");
                break;
        }

        DateTime dateTimeOfOperation = DateTime.UtcNow;
        
        MainIncomingChangesSaverList.IncomingChangesSaversList.Enqueue(new IncomingChangesSaver()

            ActionHumanString = actionHumanString,
            DateTimeOfChange = dateTimeOfOperation
        });

        using (ApplicationContext db = new ApplicationContext())
        {
            if (actionNumber == 2 || actionNumber == 5)
            {
                Pause pause = new Pause(){wcGuid = wcGuid, Operation = operation, BoxSerial = boxSerial, SkusSerial = skusSerial, ActionNumber = actionNumber, DateTime = dateTimeOfOperation};
                db.Pauses.Add(pause);
            }
            Change change = new Change() { wcGuid = wcGuid, Operation = operation, BoxSerial = boxSerial, SkusSerial = skusSerial, ActionNumber = actionNumber, DateTime = dateTimeOfOperation };
            db.Changes.Add(change);
            db.SaveChanges();
        }

        // return StatusCode(200);

Users quickly press buttons on the front, up to 1 time per second. Every time you click from the frontend, an ajax request is made.

it seems a dotnet bug, see https://github.com/dotnet/aspnetcore/issues/23949, you can use a middleware to catch the Exception, https://github.com/dotnet/aspnetcore/issues/23949#issuecomment-950471048
