I have .net 5 api which works on my machine but not on Azure App Service. It looks like its failing to write the response and following is the Exception stack trace and Startup code. I am using System.Text.Json. I am not sure whats causing this hence the question. I can see the controller action gets executed so deserialization works fine on the way in. It fails when writing response.
Specifically, it errors on calling move next in a custom middleware which calls Authentication middleware as seen in Stacktrace.
CheckRequestHeaderMiddleware+<Invoke>d__6.MoveNext
Controller action method :
try
{
request.IdFromToken = GetIdFromToken();
if (!await IsValidAsync(request, _requestValidator))
{
return BadRequest(ModelState);
}
if (!Request.Headers.Keys.Contains("X-ClientId"))
{
return BadRequest("Header X-ClientId is missing");
}
else
{
request.ClientId = Guid.Parse(Request.Headers["X-ClientId"]);
}
// Encoding to prevent xss attack
xssValidation.xssHtmlEncoding(request);
var serializedMessage = JsonSerializer.Serialize(request);
await _messagePublisher.SendAsync(serializedMessage);
return Ok();
}
catch (BadRequestException ex)
{
ModelState.AddModelError(string.Empty, ex.Message);
return BadRequest(ModelState);
}
catch (Exception ex)
{
return StatusCode(StatusCodes.Status500InternalServerError,ex);
}
