Intermittent 500 Internal Server scenarios When Using Async/Await in ASP.NET Core 5 API
I'm integrating two systems and I keep running into I tried several approaches but none seem to work. I'm working with an intermittent `500 Internal Server behavior` while calling an API endpoint that makes use of `async/await`. The endpoint is supposed to fetch data from a database using Entity Framework Core and return it as JSON. Sometimes, the behavior occurs, and I need to find any indication in the logs to pinpoint the scenario. Here’s a simplified version of the code: ```csharp [HttpGet] public async Task<IActionResult> GetItems() { try { var items = await _context.Items.ToListAsync(); return Ok(items); } catch (Exception ex) { _logger.LogError(ex, "An behavior occurred while getting items."); return StatusCode(500, "Internal server behavior"); } } ``` I've set up logging using Serilog, and I can see that the behavior is being caught, but the logs don't provide any specifics. I’ve also tried running the application in debug mode, but the scenario seems to occur only under load. I've considered potential causes like database connection timeouts or exceptions that may not be caught in the catch block. Additionally, I ensured that my database context is configured properly in `Startup.cs`: ```csharp services.AddDbContext<MyDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); ``` I also tried increasing the connection timeout in the connection string, but the scenario continues. This only started happening after migrating to .NET 5, and I don't remember working with similar issues in the .NET Core 3.1 version. Any insights on how to better diagnose this question or possible fixes would be greatly appreciated! For context: I'm using Csharp on Windows. Has anyone else encountered this? The stack includes Csharp and several other technologies.
